Question

Write an equation in slope-intercept form for the line through the two points.
(-3,6); (2,1)

Answer 1

Find the slope using the formula m = (y2 - y1) / (x2 - x1)

Then the equation of a line in slope-intercept form is: y = mx + b
Put the value of m found earlier.
This line passes through the given two points. Put any one of the points into y = mx + ba and solve for b.

Answer 2

Why is there an a in y=mx+b

Answer 3

Typo. Put any one of the points into y = mx + b and solve for b.
