Step-by-step explanation:
Answer is in the attached image.
4x+28
y=5x+4
First get slope:
(4-9)/(0-1) = -5/-1 = 5
The y-intercept is where the graph hits the y-axis. That is also the point on the graph where x = 0. We are already given that, with point (0,4).
The y-intercept is 4.
y = mx +b, m is slope and b is the intercept.
y = 5x +4
5(3x+4)=23
15x+20=23
15x=23-20
15x=3
x=3/15
x=1/5=0.2
