Question

What are the intercepts of the equation? Graph the equation. 5x+3y=15

Answer 1

To get the y-intercept, you plug in x = 0

5x+3y=15

5*0+3y=15

0+3y=15

3y=15

y = 15/3

y = 5

This means the y-intercept is (0,5)

Answer 2

To get the x-intercept, plug in y = 0 and solve for x. Tell me what you get.

Answer 3

x intercept would be (5,0)?

Answer 4

nope

Answer 5

5x+3y=15

5x+3*0=15

x = ???

Answer 6

that would make it (3,0)

Answer 7

so you now have the two points (3,0) and (0,5)

Answer 8

plot them both on the same coordinate axis

then draw a straight line through them

Answer 9
