Question

Write the equation of the line that passes through (3, –2) and has a slope of 4 in point-slope form.
A.) y + 2 = 4(x – 3)
B.) y – 3 = 4(x + 2)
C.) x – 3 = 4(y + 2)
D.) x + 2 = 4(y – 3)

Answer 1

Please help @hartnn @perl

Answer 2

the equation of line with slope = m and point = x1,y1 is
\(y-y_1 = m (x-x_1)\)

here, m = 4,
x1, y1 = 3,-2

just plug in!

Answer 3

but pay attention to that -2

Answer 4

Ohhh ok, but there's only one set of points given?

Answer 5

you need only one.

x1 = 3, y1 = -2

y - (-2) = 4 (x - 3)

Answer 6

Oh I see, thank you! :)

Answer 7

welcome ^_^
