Question

Write the equation the line through the point b) (1,3) with slope = -4

Answer 1

Below

Explanation:

Here is the point-slope form of this line to start:

y-3 = -4 ( x-1) which can be re-arranged to

y = -4x +7 which is y = mx + b form ( slope -intercept from)

or

4x + y = 7 sometimes called 'standard form'
