Question

3x-4y=-9
-x-4y=-13

Solve these linear systems by graphing, then find the point at which they intersect.

HOW DO I DO THIS!? i need help. -_-

Answer 1

Graph both lines.

Answer 2

they will definitely meet somewhere

Answer 3

how do i graph them, what do i put on the x axis and what do i put on the y?

Answer 4

3x-4y=-9


graph this line first.

Answer 5

whn x-intercepts y = 0
whn y-intercpets x = 0

Answer 6

insert the values to get the intercepts.

Answer 7

but then for the y intercept you get:
3x-4y=-9
3(0)-4y=-9
4y=-9
then you get -2.25, correct?

Answer 8

dividing both sides by 4/

Answer 9

its correct.

Answer 10

now after y-intercpet.
go for x intercpt & draw a line there.

Answer 11
