write an equation of the line x- intercept: -1, y-intercept:4
-----------
At the x-int, y = 0
At the y-int, x = 0

an equation of the line is: y=mx%2Bb where m is a slope and b is y-intercept

given:
x- intercept: -1, ->(-1,0)
y-intercept:4->->(0,4)->b=4
use these points to find a slope:
m=%28y-y%5B1%5D%29%2F%28x-x%5B1%5D%29
m=%280-4%29%2F%28-1-0%29
m=-4%2F-1
m=4
since b=4 and m=4 your equation is:
y=4x%2B4
