The y-intercept, in this case, represents when x is at 0, or when she just began observing.
Yes due to the fact that additive inverse is the oppsite. so she runs up +4 and runs down -4.
Answer:
c = 140
Step-by-step explanation:
y = -7x + 140
-7 x 0 + 140
0 + 140
c = 140
(x = 0, y = c)
(0,140)
To answer this question, we have to follow the next steps:
1. Subtract 13 to both sides of the equation:

2. Divide the resulting equation by 5 to both sides of the equation:

Therefore, the value that solves this equation is W = 21/5 or W = 4.2 (using a decimal expression.)
