Question

How do you graph using the intercepts for `7x + 4y = 17`?

Answer 1

Put zero in for both x and y solve for the other variable and then graph ( X, 0) and (0,Y) Draw a line between the two intercepts.

Explanation:

`7 xx 0 + 4y = 17`

`4y = 17`

`(4y)/4 = 17/4`

`y = 17/4 or 4 1/4`

`7x + 4 xx 0 = 17`

`7x = 17`

`(7x) /7 = 17/7`

`x = 17/7`

Plot `( 0, 17/4)` and `( 17/7 ,0)`

Connect the two points.
