Answer:

y = 4x - 3

Explanation:

1. Pick tow points that is on the line; (1, 1) and (2, 5).

2. Find the Slope: Slope = (change in the y-values)/(change in the x-values)

Slope = (5 - 1)/(2 - 1) = 4/1 = 4

3. Use the slope and one point on the graph and substitute into y = mx + b

and solve for "b"

y = mx + b Slope = 4 point (1, 1)

1 = 4(1) + b

1 = 4 + b

1 - 4 = b

-3 = b

4. Write the equation of the line: m = 4 and b = -3

y = 4x - 3
