Example Question #4 : How To Find The Slope Of A Line
If 2x – 4y = 10, what is the slope of the line?
–2
0.5
2
–5/2
–0.5
0.5
First put the equation into slope-intercept form, solving for y: 2x – 4y = 10 → –4y = –2x + 10 → y = 1/2*x – 5/2. So the slope is 1/2.
Example Question #21 : Other Lines
What is the slope of the line with equation 4x – 16y = 24?
–1/4
1/2
1/8
1/4
–1/8
1/4
The equation of a line is:
y = mx + b, where m is the slope
4x – 16y = 24
–16y = –4x + 24
y = (–4x)/(–16) + 24/(–16)
y = (1/4)x – 1.5
Slope = 1/4
Example Question #3 : Other Lines
What is the slope of a line which passes through coordinates and ?
Slope is found by dividing the difference in the -coordinates by the difference in the -coordinates.
Example Question #41 : Coordinate Geometry
What is the slope of the line represented by the equation ?
To rearrange the equation into a format, you want to isolate the so that it is the sole variable, without a coefficient, on one side of the equation.
First, add to both sides to get .
Then, divide both sides by 6 to get .
If you divide each part of the numerator by 6, you get . This is in a form, and the is equal to , which is reduced down to for the correct answer.
Example Question #222 : Geometry
What is the slope of the given linear equation?
2x + 4y = -7
-2
1/2
-1/2
-7/2
-1/2
We can convert the given equation into slope-intercept form, y=mx+b, where m is the slope. We get y = (-1/2)x + (-7/2)
Example Question #231 : Geometry
What is the slope of the line:
First put the question in slope intercept form (y = mx + b):
–(1/6)y = –(14/3)x – 7 =>
y = 6(14/3)x – 7
y = 28x – 7.
The slope is 28.
Example Question #232 : Geometry
What is the slope of a line that passes though the coordinates and ?
The slope is equal to the difference between the y-coordinates divided by the difference between the x-coordinates.
Use the give points in this formula to calculate the slope.
Example Question #233 : Geometry
What is the slope of a line running through points and ?
The slope is equal to the difference between the y-coordinates divided by the difference between the x-coordinates.
Use the give points in this formula to calculate the slope.
Example Question #42 : Coordinate Geometry
Find the slope of the line that goes through the points
Use the following formula to find the slope:
Plug in the given points to find the slope.
Example Question #1 : How To Find Out If A Point Is On A Line With An Equation
Which of the following points is on both the line
and the line
In the multiple choice format, you can just plug in these points to see which satisfies both equations. and work for the first but not the second, and and work for the second but not the first. Only works for both.
Alternatively (or if you were in a non-multiple choice scenario), you could set the equations equal to each other and solve for one of the variables. So, for instance,
and
so
Now you can solve and get . Plug this back into either of the original equations and get .
