M= (7-1)/(2-0)=3
y=3x + c
plug in Q 
1= 3 x 0 +c
=> c =-2
=> the equation represents line QR is y=3x -2

y – 1 = 3x

since Q is (0,1) that would make 1 the y-intercept.

using a formula to find the slope we end up with 3.

1 is a negative because when moved to the other side it must be positive.

Answer:

The slope formula can be used to prove that a triangle has

A. Congruent Sides

<u>B. A right angle </u>

C. Parallel sides

D.Congruent angles

Step-by-step explanation:

The formula for finding the slope of a line on a coordinate plane is (y2 - y1) / (x2 - x1), where (x2, y2) and (x1, y1) represent two distinct points on the line. This is also known as "change in y over change in x" or "rise over run."
