Question

Graph the line of the equation
5x + 3y =-15
ow did you know to put -5 and - 3 ? did you change it because the answer equals -15?

Answer 1

when x = 0, y is

5x + 3y = -15

5(0) + 3y = -15

0 + 3y = -15

3y = -15

y = -15/3

y = -5

So the y-intercept is (0, -5)

Answer 2

To find the x-intercept, you plug in y = 0 and solve for x

Answer 3

Thanks i'll try my best!

Answer 4

np

Answer 5

would you use y=mx + b? in this situation?
