Question

...how do i do this?...


Graph 3x + 9y = -21 and check on your calculator.

What is the x-intercept, the y-intercept, and the slope?

Answer 1

x-intercept is the x value when y equals to 0. Y-intercept is the y value when x equals to 0. the slope is -1/3

Answer 2

So X =-7
and Y = -2.33?

Answer 3

so basically x-int = - 7, y-int = -7/3, m = -1/3 no?

Answer 4

yep

Answer 5

Alright cool Thanks Dude!

Answer 6

small mistake..it;s not -1/3

Answer 7

9y = -21
y = -21/9
y = -7/3
