Question

Write the slope-intercept form of the equation of the line (y=Mx+b) through the given point:

(-3,0) and (-2, 2)

Answer 1

y = 2x + 6

Explanation:

`M=(y_2-y_1)/(x_2-x_1)=(2-0)/(-2-(-3))=\frac21=2`

y = 2x + b passes through point (-3, 0), so:

0 = 2(-3) + b

0 = -6 + b

b = 6

Therefore the equation: y = 2x + 6
