NEED HELP WILL MARK BRAINLIEST IF CORRECT!!

A OR C

Step-by-step explanation:

1 Use Rule of One: {x}^{1}=xx

1

=x.

m=\frac{{y}^{2}-y}{{x}^{2}-{x}^{1}}m=

x

2

−x

1

y

2

−y

2 Factor out the common term yy.

m=\frac{y(y-1)}{{x}^{2}-{x}^{1}}m=

x

2

−x

1

y(y−1)

3 Use Rule of One: {x}^{1}=xx

1

=x.

m=\frac{y(y-1)}{{x}^{2}-x}m=

x

2

−x

y(y−1)

4 Factor out the common term xx.

m=\frac{y(y-1)}{x(x-1)}m=

x(x−1)

y(y−1)

y=mx+b

step-by-step explanation:

m slope, b y-intercept
