Question

What is the answer for finding the slope from two points. Please help I am very confused

Answer 1

Slope = $\frac{y2 - y1}{x2 - x1}$
------------------
Substitute as followed
y2 = 4
y1 = 1/2
x2 = 1/2
x1 = 2
Slope = $\frac{4- \frac{1}{2} }{ \frac{1}{2}-2}$
--------------------------
Solve
4 - 1/2 = 7/2
1/2 - 2 = -3/2
$\frac{7/2}{-3/2}$
-7/3 = slope
