Equation of a line for 1,3 and -3,5

Mathematics
1 answer:
astra-53 [7]3 years ago
4 0

Answer:

y = -1/2x +7/2

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

   = (5-3)/(-3-1)

   = 2 /-4

   = -1/2

We can use the slope intercept form

y= mx+b where m is the slope and b is the y intercept

y = -1/2 x+b

Substitute the point int

3 = -1/2 (1) +b

3  = -1/2 +b

Add 1/2 to each side

62 + 1/2 = b

b = 7/2

y = -1/2x +7/2

The Federal Bureau of Investigation is not an agency under the direction of the Department of Homeland Security. The correct option among all the options that are given in the question is the third option or option "c". FBI is actually the domestic intelligence and security agency. I hope the answer comes to your help.
