Answer:

y = 50x + 75

Step-by-step explanation:

A linear equation can be written as:

y = mx + b

where

m = slope

b  = y-intercept

x and y = coordinates (x, y)

We know the y-intercept is (0, 75) by looking at the graph, so plug 75 in for b.

y = mx + 75

Then we can find the slope by finding the [tex]\frac{rise}{run}[/tex]

Choose any two points - we can use (0, 75) and (1, 125)

We can use the equation [tex]slope = \frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute the points - [tex]\frac{125-75}{1-0}[/tex]

= 50

Substitute 50 for m

y = 50x + 75
