Answer:
C y = 4x + 5
Step-by-step explanation:
use y = mx + b
we need m and b to complete the equation.
m = slope
b = y-intercept (when x =0)
(0, 5) is the y-intercept because that's when x = 0
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m = \frac{9-5}{1-0} = \frac{4}{1} = 4[/tex]
slope is 4
so... y = 4x + 5
