40×8=320[ 8×3=24 ]320+24=344
Answer:
y=1/2x
Step-by-step explanation:
The slope of the line goes up by 1 over by 2 each time or 1/2. (Rise over run)
This can be proven by substituting X and Y for a point on the graph.
y=5, x=10
5=1/2(10)
5=5
-7(2)+y=60
-14+y=60
y=60+14
Y=74
Answer:
Step-by-step explanation:
The slope of a line given two points 
and 
is
I can't see the options, but you would need to multiply (4x - 2y = 7) by 3, and (3x - 3y = 15) by 4 so that you get 12x in both equations. Then when you subtract, you eliminate 12x. I hope this helps!
