Question

Write an equation in point-slope form of the line that passes through the point (4,−9) and has a slope of 6. The equation is y− = (x− )

Answer 1

y + 9 = 6(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 = 6 and (a, b) = (4, - 9), thus

y - (- 9) = 6(x - 4), that is

y + 9 = 6(x - 4)
