Question

Find the equation of a line in point slope form with a slope of 3 going through the point (4,-6)?

Answer 1

y + 6 = 3(x - 4)

Explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = 3 and (a, b) = (4, - 6), hence

y - (- 6) = 3(x - 4), that is

y + 6 = 3(x - 4) ← in point- slope form

Answer 2

Equation of line: y=3x-18

Explanation:

Point: (4,-6) and slope = 3

`y+6=3(x-4)`

y=3x-18
