Question

Choose the equation below that represents the line passing through the point (-3, -1) with a slope of 4.

y = 4x - 11
y = 4x + 11
y = 4x + 7
y = 4x - 7

Answer 1

WILL FAN AND MEDAL

Answer 2

Plug in the -3 for x and -1 for y

since the slope is the same in all equations - can not eliminate up front

Answer 3

-1 = 4(-3) + m
-1 = -12 + m
-1 + 12 = m
11 = m

which tells me the y - intercept is 11 - so therefore B is the correct answer

Answer 4

thanks but how did you get the y-intercept (my first year of online homeschooling and it's not very easy)

Answer 5

I just solved for B (I used M but should of used B)
note
Y = mx + b

M = slope
B = y-intercept

so if you are give Y, M, and X solve for B
