Answer:
Step-by-step explanation:
$0.70 per mile is the rate (slope), $10 flat fee is your starting cost (i.e. your y-intercept).
By slope - intercept linear equations we have:
(a) y=mx+b where m is the slope and b is the y-intercept.
y=0.70x+10
(b) The graph is linear on the coordinate plane because the slope (rate) is constant.
(c) The slope of this graph is $0.70 per mile and the y-intercept is $10 flat fee. Your cost is $10 initially and $0.70 for every mile driven.
Answer:
Step-by-step explanation:
Equation: y=0.70x + 10
It forms an increase in cost so the line slants upward.
Slope: The increase in miles per hour which is 0.70x
Intercept: Is the starting point on the y-intercept for which the line starts.Which is where the 10 comes in.(0, 10)

Answer:
Area = length x width
width = 1/2 length = 12/2 = 6 = width
area = 6x 12 = 72
