Construction crews are building a highway. Currently the highway is 12 miles long. Each month the total length increases by 3 miles. Which equation can be used to find y, the total length of the highway in miles after x months? y=3x+12
y is equal to 3 x plus 12

y=15x
y is equal to 15 x

y=12x+3
y is equal to 12 x plus 3

y=12x−3
