Du 4. The graph of a linear function passes through the origin and a point at (15, 75). Which equation represents the function?
&
о
y = 152 + 75
20
О
y = 5.2
O
y = 50 + 75
o
y = 75.22

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
