That #'s that you give us is the coordinate?? Like is going to be (6, -2) and (-4,6)
Answer:
for 1. -30 - 12 = -42
Step-by-step explanation:
You can graph it with the calculator or on graph paper and see where the two lines would cross
you would put them in slope-intercept form (y=mx+b)
so
2x + y = 4 would become
y = -2x + 4
and
2y = 6 - 2x becomes
y = -x +3
graph them and see where they cross. hope this helps!!

Step-by-step explanation:
for every single problem you times the hours by 10× then the drones by 40× Thank me later
Hey there! I'm happy to help!
We want to find the equation of a line in y-intercept form, which is y=mx+b, where x and y are a point on the line, m is the slope, and b is the y-intercept.
We already know that our slope is -3.
y=-3x+b
We want to solve for b now. We can plug in our point (-9,-9) to solve for it.
-9=-3(-9)+b
-9=27+b
b=-36
So, our equation is y=-3x-36.
I hope that this helps! Have a wonderful day! :D
