Question

Write an equation for this graph

Answer 1

Answer: y=3x

Explanation:

To write an equation, the first step is to look at the rise/run. In this graph, the rise is 3 and the run is 1. 3 divided by 1 is still 3 so in the equation mx+b, the m, also known as the slope, would be 3.

3x+b

And the b is the y-intercept where the line crosses the y axis.

3x+0=y

Therefore;

3x=y

Answer 2

y = 3x

Explanation:

m = (6-3)/(2-1) = 3/1 = 3
