Answer:
Step-by-step explanation:
Slope-intercept form equation is given as
Where,
y = distance remaining
x = hours driven
m = slope/constant rate. In this case, the value of m would be -65. This means the distance will reduce at a constant rate of 65 miles per hour.
b = y-intercept, which is the initial value or the distance between the cities = 420
Plug in the values into the slope-intercept equation, to represent the distance y in miles remaining after driving x hours. You would have:
Answer:
scale factor = 4
Step-by-step explanation:
The ratio of corresponding sides, blue shape to black shape.
The corresponding widths are 1 and 4 , then
scale factor = = 4
