Question

Write the equation of the line that passes through the point (6,4) and has a slope of -2 in standard form

Answer 1

y = -2x + 16

Explanation:

The line passes through (6,4)

And has a slope of -2

Taking another point (x,y) on the line;

Slope(m) = change in y ÷ change in x

-2 =
`(y - 4)/(x - 6)`

Cross multiplying gives;

y - 4 = -2x + 12

y = -2x + 16
