Question

Look at the graph shown:

(Graph down below)

A coordinate plane is shown. A line passes through the y-axis at -1 and through the point 1 comma 2.
Which equation best represents the line?

y = 1 over 3. x − 1
y = 3x − 1
y = −x + 1 over 3.
y = 3x + 1

Answer 1

y = 3x − 1

Explanation:

Answer 2

it's y-intercept (0,-1) and (1,2)
so
slope = (2+1)/(1-0) = 3

equation should be y = 3x − 1

answer: y = 3x − 1
