You see that this equation is not written explicitly in terms of 
First, add 
Then subtract 
Finally, divide by 
Now that the equation is explicitly in terms of 
In this equation, 
Since the y-intercept is a point, we will want to write it in point notation: 
Example Question #21 : How To Find Slope Of A Line
There are two points: 
If these points are connected by a straight line, what is the slope of this straight line?
To determine the slope, we use the following formula.
In the formula, the two points making up that slope are 
The slope is 
Example Question #21 : How To Find Slope Of A Line
Find the slope of the line that passes through the points (0,2) and (5,-2).
To find the slope of the line passing through the given points, we need to find the change in y and divide it by the change in x. This can also be written as 
Example Question #23 : How To Find Slope Of A Line
Find the slope of the line using the following given points:
(2,5), (5,6), (8,7)
To find the slope, divide the change in 
So,
Check your answer by using the same equation on another pair of points:
It's the same! So the answer is 
Example Question #24 : How To Find Slope Of A Line
What is the y-intercept of the line
To easily determine an equation's y-intercept, convert it to the 
Converting the given equation to this form gives you
with a y-intercept of 
Example Question #25 : How To Find Slope Of A Line
The line given by the equation 
The equation 
From here, it can be deduced that the slope is 
Example Question #32 : Properties Of Functions And Graphs
What is the slope of the line depicted by this equation?
This equation is written in standard form, that is, 
In this instance 
This question can also be solved by converting the slope-intercept form: 
Example Question #26 : How To Find Slope Of A Line
What is the slope of a line if the points on the line are 
Write the formula to find slope.
The values are interchangable as long as they are in the correct order.
The formulas yield similar slopes.
The correct answer is 
Example Question #21 : How To Find Slope Of A Line
Fnd the slope of the following equation:
To find the slope, we need to get the equation in the form of 
Add 
Divide both sides by 7.
Now we can see that our slope is the coefficient in front of the 
Example Question #3712 : Algebra 1
Find the slope of the following equation:
Remember that the equation of a line is given as 
To get out equation in that form so we can identify what our 
Now, to get just 
Now, we can easily identify our slope as
