Each section of a running trail is 3/4 miles. the trail has 3 sections.
which expression tells how many miles long the entire trail is?

3/4 times 3

Step-by-step explanation:

3/4 time 3 sections is 2 and 1/4  miles long

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
