Answer:
B. y = 2/3 x.
Step-by-step explanation:
The slope of the line = rise / run = 2/3.
The equation is y = 2/3 x.
First, lets break down the sample equation: y=-2x+7
-2=m=slope
+7=b=Y-intercept
Using process of elimination:
A is not perpendicular because the angle created by slopes is unequal to 90
B and D are quadratic equations, and have no correlation with the sample equation
C is parallel to the sample equation
Is there a typo in your question? None of these answers are correct, but I am wiling to keep helping you, I enjoy Algebra.
Answer:
The choice four;
Step-by-step explanation:
We have to reverse what was already done to the number 19, so we’ll multiply it by 3 to get 57. We then subtract 8 from it to get 49. Therefore, the original number is 49.
