A line passes through the points (-5, 2) and (10.-1). Which is the equation of the line?
y=-3x+1
lo y = 13x + 3
y=-5x - 23
y = 5x + 27
O

y = -1/5x +1

Step-by-step explanation:

First we need to find the slope

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

   = (-1 -2)/(10 - -5)

    = -3/(10+5)

    = -3/15

    = -1/5

Then we can use point slope form

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

y = -1/5x +b

Substitute a point into the equation

2 = -1/5(-5) +b

2 = 1 +b

Subtract 1 from each side

1 =b

y = -1/5x +1

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
