Answer:
y=4x+40
Step-by-step explanation:
slope equals 4
x-intercept= -10
y=mx+b for the x-intercept the y equals zero so plugging zero the y and -10 to the x
0=4(-10)+b
0=-40+b now you isolate the variables
b=40 so the equation is y=4x+40 because you have the slope you just pluggin the numbers to the equation
