Example Question #1 : How To Find Slope Of A Line
What is the slope of the equation 4x + 3y = 7?
–4/3
–7/3
–3/4
3/4
4/3
–4/3
We should put this equation in the form of y = mx + b, where m is the slope.
We start with 4x + 3y = 7.
Isolate the y term: 3y = 7 – 4x
Divide by 3: y = 7/3 – 4/3 * x
Rearrange terms: y = –4/3 * x + 7/3, so the slope is –4/3.
Example Question #71 : Slope And Line Equations
Find the slope of the line through the points (6,2) and (3,4).
The equation for slope is . You plug in the coordinates from the points given you, and get , giving you . Note that it does not matter which point you use as point 1 and point 2, as long as you are consistent.
(6,2) = (x_{1},y_{1})
(3,4) = (x_{2},y_{2})
Example Question #2 : How To Find Slope Of A Line
Given the line 4y = 2x + 1, what is the slope of this line?
1/4
–2
2
1/2
–1/4
1/2
4y = 2x + 1 becomes y = 0.5x + 0.25. We can read the coefficient of x, which is the slope of the line.
4y = 2x + 1
(4y)/4 = (2x)/4 + (1)/4
y = 0.5x + 0.25
y = mx + b, where the slope is equal to m.
The coefficient is 0.5, so the slope is 1/2.
Example Question #3 : How To Find Slope Of A Line
What is the slope of the line containing the points (7,12) and (91,32).
To find the slope of a line you must first assign variables to each point. It does not matter which points get which variables as long as you keep the and and and consistent when you plug them into the equation.
Then we plug in the variables to this equation where represents the slope.
Then we plug in our points for and the example looks like
Then we perform the necessary subtraction and division to find an answer of
