What is the y-intercept of the line that passes through the points (2,-1) and (-3,9)

The equation of the straight line y = -2x +3

y-intercept =  3 and m =-2

Step-by-step explanation:

Step(i):-

Given that the points are ( 2,-1) and (-3,9)

The slope of the line

Step(ii):-

The equation of the straight line passing through the point ( 2,-1) and slope m=-2

      y-y₁ = m( x- x₁)

     y -(-1) = -2 ( x-2)

      y +1 = -2x +4

     2x +y +1-4 =0

    2x +y -3 =0

Final -

The equation of the straight line y = -2x +3

answer: your gay

step-by-step explanation:

you dont know math

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
