Question

5. What is the equation of the line that contains the points with (x, y) coordinates (–3, 7) and (5, –1)?
A. y = 3x – 2
B. y = x + 10
C. y = –x + 4
D. y=−1/3x+8 E.
y=−3/2x+114

Answer 1

and how did you get the answer

Answer 2

C. y=-x+4 leave the choices find equation of line by two point form and u will see it is y=-x+4

Answer 3

first u have to find the slope (do u know how to find the slope??)
-1-7/5+3
-8/8
-1
second u choose any of the points u have (5,-1) ,(x,y)
then u substitute theses points in the form y=mx+b ( the 5 by x and the y -1 ) to find the y-intercept which is b
-1=-1(5)+b
-1=-5+b
-1+5=b
4=b
so we got the y-intercept
and we put it again in the form y=mx+b
y=-x+4

Answer 4

did u understand??

Answer 5

thanks a lot :)
