What is an equation for the line that passes through the coordinates 2,7 and 0,1

Answer 1

y = 3x+1

3x -y =-1

Answer 2

First, find the slope of the line.

Slope = rise / run

Slope = ΔY/ ΔX, where ΔY = 7-1 and ΔX = 2-0

Slope = 6/2 = 3

Second, find the y-intercept.

You are given the coordinate pair (0,1), so you know that the y-intercept is at y=1.

Third, plug into the formula y=mx+b

'm' is the slope of your line and 'b' is the y-intercept. So, the equation for the line is:

y=3x+1
