Choose the system of equations that matches the following graph: will insert pic below a) x − 4y = −4 3x + 4y = 36 b) x + 4y = −4 3x − 4y = 36 c) x + 4y = −4 3x + 4y = 36 d) x − 4y = −4 3x − 4y = 36

Red line
slope m = 1/4
y=(1/4)x+b
b is y-intercept, b=1

y=(1/4)x+1
To get it the for that are given in the problem multiply both sides by 4.
4y=x+4,   or x-4y=-4 red line

blue line
slope m=-3/4
y-intercept b= 9
y=-(3/4)x+9
4y=-3x+36
3x+4y=36 blue line

x-4y=-4 red line
3x+4y=36 blue line
A) x − 4y = −4, 3x + 4y = 36
