Answer:
Your x-intercept would be E, -4
Step-by-Step
To find the x-intercept, set y=0.
Our problem:
y=5x+20
0=5x+20
To get the variable term on its own you need to move your 20 over by subtracting it from the right and moving to the left making it -20.
-20=5x
Divide by 5 to get x on its own
-20/5= 5x/5
-4=x
x=-4
