Question

Select the graph that matches the equation y = 8
5
10
x + 9.

Answer 1

option C

Explanation:

y = mx + b → y = 8.5x + 9

b is the y intercept: 9

m is the slope: 8.5

to identify this on the graph, the y intercept is when x = 0

crossing the vertical bold (y) line

so which one is at 9? c is the only one at 9
