The distance traveled by a small car varies directly to the amount of fuel it consumes. The small car traveled 120 miles on 3 gallons of fuel. At the same rate, how far would the small car travel on 7 gallons of fuel?
O 141 miles
0 280 miles
Z
0 130 miles
O 480 miles

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

no its the same as every other grade

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
