Slope - Intercept Form of a Line:
y = mx + b
where m is the slope and b the y - intercept.
Given the points: (-2, 5) and (2, 1):
To find m:
[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{1-5}{2+2} \\ m\text{ = -1} \end{gathered}[/tex]To find b:
1 = -1(2) + b
b = 1 + 2
b = 3
EQUATION OF THE LINE:
y = -x + 3
