Respuesta :
to find the x intercept, sub in 0 for y and solve for x
-2x + 5y = -20
-2x + 5(0) = -20
-2x = -20
x = -20/-2
x = 10...so ur x int is 10 or (10,0) <==
-2x + 5y = -20
-2x + 5(0) = -20
-2x = -20
x = -20/-2
x = 10...so ur x int is 10 or (10,0) <==
Normally, to find the X intercept, you make the Y zero. So now you have -2x=-20. And divide both sides by -2. So X=10. If you wanted to plug 10 in, you could. But you wouldn't really need to. At least you didn't have to when I took Algebra 1.
