Question

how would you get the coordinets on a graph from the equation... y=3/4 -3?

Answer 1

I assume you mean y= (3/4)*x -3
to get (x,y) pairs, pick a value for x, and then do the arithmetic to find y.

Hint: pick easy numbers for x to make the problem easy.
For example, with x=1
y = (3/4)*1 -3 = 3/4 - 3 = -9/4
and one pair is (1, -9/4)

Answer 2

so then i just do that twice for each equation and graph it?

Answer 3

yes. easy as pie!

Answer 4

wait i still dont understand

Answer 5

oh im sorry its upside down

Answer 6

If you use x=4, and x=-4 you will get nicer numbers for y
y = (3/4)*4 -3 = 3-3 =0
y = (3/4)* -4 -3 = -3 -3 = -6
so use (4,0) and (-4,-6)
