Answer:
x = 15
Step-by-step explanation:
given that y varies directly with x
mathematically we can express this as
y = k x , where k is a constant
step 1: find k
given x = 3 and y = 21
y = k x
21 = k (3)
k = 7
hence the equation becomes
y = 7 x
when y = 105,
105 = 7x
x = 105 / 7 = 15
1/3
because a foot is a third of a yard and a yard is 3 feet.

Answer:
slope=1
Step-by-step explanation:
Formula for slope is m =
y2 - y1
/x2 - x1
you will then use 7-8/4-5
Then -1/-1 which will simplify to 1
