Question

Identify the x and y intercepts for the equation 3x + 4y = 12.

Answer 1

when x intercpts, y = 0

when y intercpts, x = 0

Answer 2

huh?

Answer 3

when x intercpts, y = 0
3x + 4y = 12.
3x + 4(0) = 12
3x = 12
x = 12/3
x = 4

when y intercpts, x = 0
3x + 4y = 12.
3(0) + 4y = 12
4y = 12
y = 12/4
y = 3

Answer 4

So,
(4,0) & (0,3)

Answer 5

o.O oh

Answer 6
