Example Question #2 : How To Find The Slope Of A Line
What is the slope of line 3 = 8y - 4x?
2
0.5
-0.5
-2
0.5
Solve equation for y. y=mx+b, where m is the slope
Example Question #2 : How To Find The Slope Of A Line
Find the slope of the line 6X – 2Y = 14
3
-3
-6
12
3
Put the equation in slope-intercept form:
y = mx + b
-2y = -6x +14
y = 3x – 7
The slope of the line is represented by M; therefore the slope of the line is 3.
Example Question #3 : How To Find The Slope Of A Line
If 2x – 4y = 10, what is the slope of the line?
–0.5
–5/2
–2
0.5
2
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 #1 : How To Find Slope Of A Line
What is the slope of the line with equation 4x – 16y = 24?
1/4
1/8
–1/4
1/2
–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 #11 : How To Find Slope Of A Line
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 #12 : How To Find Slope Of A Line
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 #3 : How To Find The Slope Of A Line
What is the slope of the given linear equation?
2x + 4y = -7
-1/2
-2
-7/2
1/2
-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 #13 : How To Find Slope Of A Line
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 #11 : How To Find Slope Of A Line
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.
