Question

Indicate in standard form the equation of the line passing through the given points.

P(6, 2), Q(8, -4)

Answer 1

First we need to workout our gradient or m value
m=y2-y1/x2-x1
m=(-4-2)/(8-6)
m=(-6)/(2)
m=-3

next we can form the equation by using the formula
y-y1=m(x-x1)
y-2=-3(x-6)
y-2=-3x+18
y=-3x+20 (gradient and intercept form)
y+3x=20(standard form)
