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 Which of the following statements best describes the effect of replacing the graph of f(x) with the graph of f(x) − 5? The graph shifts 5 units up. The graph shifts 5 units down. The graph shifts 5 units left. The graph shifts 5 units right.
You doing FLVS?
yep homeschooling
What lesson?
Math Module 3 3.09
can someone viewing this question help me answer these two questions plz
Ok for first question, find out where (-3, -1) can fit in those equations.
???
Just plug in -3 for x and -1 for y, and see if they match
I got -12 +b = -1
Here, let's do the first one: y = 4x − 11 -1 = 4(-3) - 11 -1 = -12 -11 -1 does not equal to -23 So A cannot be the answer
where did the 11 come from?
11 was there in that equation from the options you gave, remember?
oh I see
Yeah, so A cannot be the answer. Try doing B now
B is correct
I got -1 = -1
Yup :)
thx :)
No problem. Now let's do the second question
ok
I think the answer is that it shifts down
Yeah I think so too
So answer should be B
ok is their proof to see if this is right. I need to get a 70% or higher in order to do my DBA with my teacher
btw I fanned you
k thanks. I also want to ask if their is a straight line on the graph is the slope undefined or 0?
The slope is undefined when it is a vertical line. 0 is when it is horizontal
ok thanks
No problem :)
kk see you around and thanks so much. I'll let you know if I got them right :D
