Answer:
Perimeter of Square Q = 49
Step-by-step explanation:
given:
sides P:Q = 2:7
side length of P = 3.5.
First, determine length of side Q by using the ratio

The perimeter is 4 times the length of the side
So, Perimeter of square Q = 4 *(7*3.5)/2 = 49
solve for "y" so it is in the form y = mx + b. "m" is the slope and "b" is the y-intercept.
ax + by = c
by = -ax + c <em>subtracted "ax" from both sides</em>
y = (-a/b)x + c/b <em>divided both sides by "b"</em>
Answer: slope is -a/b and y-intercept is c/b
