Question

line ab passes through points a(–6, 6) and b(12, 3). if the equation of the line is written in slope-intercept form, y = mx b, then m = – and b =

Answer 1

The answer is:
m=-3/18 and b= 5

Answer 2

y=mx+b where m is the slope;
m=$\frac{y}{x}$
m=$\frac{6-3}{-6-12}$
m=$\frac{3}{-18}$
m=$\frac{-1}{6}$

Calculating value of b;
Using point (-6,6)
$y= \frac{-1}{6} x+b$
6=$\frac{-1}{6} *(-6)+b$
b=5
