Answer:
C
Step-by-step explanation:
You can use the formula y=mx+b
f(x) is the same as y
m=slope
b=y intercept
We know that the slope is -2 so which answer has -2 as b? (Which one has a -2 before the x?)
Y Intercept is where the line crosses though the y axis. The point of the y intercept will ALWAYS have 0 as x. So (0,4) is the y intercept. You could also say 4 is the y intercept. Which one has 4 as b? (Which one says +4 after -2x)
The only answer that matches is C.
I hope thay made sense.
(3/10) in = (7/8) mi
1 in = (7/8) mi ÷ (3/10)
= 7/8 * (10/3) = 70/24
1 in = (70/24) mi
It means every 1 inch on the map drawing represents (70/24) miles ≈ 2.917 miles in reality.
Answer: The simplest form of 35/40 is 7/8.
