B- Not sure if it's a line
C- y=(-x/2)-6
D- y=4x-12
E- y=(2/5)x-10
Answer:
(C) - 3x²+6
Step-by-step explanation:
(2x²+3x-4) +(8-3x) +(-5x²+2)= 2x²<em>+3x</em><u>-4 +8</u><em>-3x</em>-5x²<u>+2 </u>= - 3x²+6
Always use the formula (y2-y1)/(x2-x1) to find a line’s slope, given two points:
(-1- -8)/(4-5) = 7/-1 = -7
-7 is the slope
Answer:
5:10
Step-by-step explanation:
because 5 is half of ten and 1 is half of 2
