Question

Select the equation of the line that passes through the point (–2, 1) and has slope 3 in point-slope form.


(y + 1) = 3(x – 2)











B.


(y – 1) = 3(x + 2)











C.


(x + 2) = 3(y – 1)











D.


(x – 2) = 3(y + 1)

Answer 1

B ><?

Answer 2

correct.
if the line has an equation of y = mx + c, then the slope is m
if the line passes through the point (a, b), you can substitute x = a and y = b into the equation

Answer 3

y - y1 = m(x - x1)......with slope(m) = 3 and points (-2,1)
y - 1 = 3(x - (-2)
y - 1 = 3(x + 2) correct...it is B.
