Question

Find the x- and y-intercepts -4x-5y=30

Answer 1

to find the x int set y to zero and solve for x.
to find the y int set x to zero and solve for y

Answer 2

x int: -4x-5(0)=30
-4x=30, divide both sides by -4 and you get: x=-15/2, so xint is (-15/2,0)
y int: -4(0)-5y=30
-5y=30, divide both sides by -5 and you get y=-6, so y int is (0,-6)
