Question

Use the following graph to answer questions 1-3.

Answer 1

1.  the slope of the line is rise/ run

pick two points  change in y/ change in x

we go up 7 and to the right 5

up and right are positive (down and left are negative)

  m = 7/5

2.  The y intercept is where we cross the  y axis  (x=0)

it is called b

b=7

(0,7)

3.  y=mx+b

y = 7/5 x+7

this is in slope intercept form
