Question

Which of the following has a slope of –3 and a y-intercept of –5?









A.

y = –3x – 5








B.
y = 3x + 5







C.

y = –3x + 5








D.

y = 3x – 5

Answer 1

y = mx + b
m is slope
b is y-intercept

Answer 2

is it a or b

Answer 3

y = (-3)x + (-5)
And, yes, it does simplify to A

Answer 4

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









A.

(y + 1) = 3(x – 2)








B.

(y – 1) = 3(x + 2)








C.

(x + 2) = 3(y – 1)








D.

(x – 2) = 3(y + 1)

Answer 5

Point-slope form is y - y1 = m(x - x1)

Answer 6

Where slope is m and a point it passes through is (x1,y1)

Answer 7

Any ideas, @drewsean ?
