Find the x-intercept of the following linear equation:

The x-intercept is where a line crosses the x axis. At the x-intercept the y value must be equal to 0.

To find our x-intercept, we are going to plug in 0 for y and solve.

Next, divide by 16.

So as an ordered pair, our answer is:

Two parallel lines have the same slope, or are both vertical. Since the first line has slope , a line parallel to this line must have slope also.

Recall what the slope-intercept form of an equation looks like:

Start by writing the equation in point-slope form:

Simplify this equation and re-write it into slope-intercept form.

Since the value of  is , the y-intercept is located at .

Recall the point-slope form of the equation of a line:

, where  is the slope, and  is the given point.

Put the given line into point-slope form.

Rearrange the equation so that it is in slope-intercept form.

Since , the y-intercept must be at .

Start by writing out the equation of the line in point-slope form.

Rearrange the equation into slope-intercept form.

Now, since , the line's y-intercept must be located at .

If we want to find where the equations intercept, you need to set them equal to each other. So, 

becomes,

Subtract 1 from both sides to get the variable by itself,

Divide both sides by 3,

gives us our final answer of

Step 1: Recall the formula to find slope:

Step 2: Find the values of  .

According to the problem: 

Step 3: Plug in...

First we need to recognize that the slope intercept form is

where  is the slope and  is the y-intercept.

Our equation has a 3 in front of the y so first we need to get rid of it so that we have a coefficient of 1. We do this by dividing both sides of the equation by 3

Now we have our equation in slope intercept form. We can now identify the slope as 2 and the y-int as -10.

Next we need to find the x-int and we do so by plugging in 0 for y and solving for x

We need to follow order of operations, so first add 10 to both sides

Now we need to divide both sides by 2 and solve for x

The x-int is 5

First we need to recognize that the slope intercept formula is

In our equation there is  in front of the y, but we need it to have a coefficient of 1 so we need to multiply both sides of the equation by the reciprocal which is 

On the left side of the equation the fractions cancel each other out to be 1. On the right side of the equation we distribute the 2/1 to both terms 

Now we have our equation in slope intercept form and we can identify the slope as -1 and the y-int as -34.

Next we need to find the x-int which we do by plugging in 0 for y and solving for x

Following order of operations, first we add 34 to both sides

Next we need to divide both sides by -y so that we can solve for x

Our x-int is -34.

Tip: Don't forget that whenever we see a variable without a coefficient, we know that it has an invisible 1 in front of it, or in this case since there is a negative sign in front of the x, we know that there is an invisible -1

First we need to recognize that slope intercept formula is

where  is slope and  is y intercept.

Our equation has  in front of the y and we need to get rid of it so that we have a coefficient of 1. In order to do this we need to multiply both sides of the equation by the reciprocal which is  

The fractions on the left cancel each other out and become one. The 4

 is distributed to both terms on the right

Now our equation is in slope intercept form and we can identify our slope as 2 and our y-int as -24.

Next we need to find the x-intercept and we do so by plugging in 0 for y and solving for x.

Now we follow order of operations, first by adding 24 to both sides

Next we divide both sides by 2 and solve for x

our x-intercept is 12
