Question

Use the point in the graph to find the equation of the line in point-slope form

A

y-3=5(x-1)


B

y+3=5(x+1)


C

y+3=5(x-1)

D

y-3=5(x+1)

Answer 1

A

Explanation:

The equation of the graph in the slope intercept form is

y = 5x -2

The slope is 5. If you start at the y-intercept (0, -2) and go up 5 and 1 to the right you will be at the red point (1,4). The slope is the rise over the run.

`(5)/(1)` = 5.

The y -intercept is where the line crossed the y axis (0,-2)

The y intercept is -2

A

y - 3 = 5x - 5 Add 3 to both sides

y - 3 + 3 = 5x - 5 + 3

y = 5x -2
