Question

Solve the system by graphing.

( I will attach pictures ) *

Answer 1

make those two equations in your problem into lines that look like y = mx + b

that makes them easier to graph...

Answer 2

I don't understand how to ?

Answer 3

So, would it look like y=-3x+-10 ?

Answer 4

example:
-3x - y = -10
Multiply everything by (-1)
3x + y = 10
Then subtract 3x from both sides:
y = -3x + 10
Now you can graph that... it's a line with slope -3 that intersects the y axis at 10

Answer 5

close... you just had the signs mixed up.

Answer 6

I still don't understand which graph it would be?

Answer 7

Can you graph y = -3x + 10?

Answer 8

I don't know how to graph it. That's what I don't understand.

Answer 9

what class is this?

Answer 10

algebra 2 . I take classes online so I don't have a teacher in front of me :/

Answer 11

that's fine... but in algebra 1, you should have done lines in slope-intercept form,
like y = mx + b

the slope is m, which is the amount it goes up or down, divided by the amount it goes left or right.

A slope of -3 means it goes down 3 for every 1 it goes to the right.

And the y-intercept is "b", meaning that is where the line crosses the y axis.
