Answer:
Step-by-step explanation:
Given points:
1. Find the slope
The slope of a line between two points equals the change in the points' y-coordinates (rise) over the change in their x-coordinates (run).
The coordinates of point 1 are:
The coordinates of point 2 are:
To find the slope, plug the points' x and y-coordinates into the formula and combine to simplify:
Step-by-step explanation:
let f(x)=y
y=7x-13
y+13=7x
y+13/7=x
f-1(x)=x+13/7
m is the slope and b is the y-intercept
10/4 I think
And simplified would be 5/2
