Answer:
Lissette biked 
Step-by-step explanation:
Let
x -----> the number of miles Shane biked
y -----> the number of miles Lissette biked
we know that
-----> equation A
----> equation B
Equate equation A and equation B and solve for y

Convert to mixed number

1: 21
2: 4a
3: m^2
4:4x+4
5:7d+21
6:y(y+3)
7:x+1
8:d+4
9:y+3
seems u got answers for the rest so i will not answer them
it has a y intercept of 3 therefore, it needs to pass the y axis through 4 3 and it has a gradient of 2 so you would start at the 4 on the y axis go across 1 and go up and keep doing it. Or cu could
Switch numbers from -2 to 2 into x into the equation to get x and y co-ordinates and then you could plot it. So it would be
when x is -2, y is -1 (-2,-1)
when x is -1, y is 1 (-1, 1)
when x is 0, y is 3 (0,3)
when x is 1, y is 5 (1,5)
when x is 2, y is 7 (2,7)
False would be the answer
