(-3,6) (-4,3) make equation

y=3x+15

Step-by-step explanation:

y2-y1         6 - 3                3

=    =   =  3

x2- x1        -3 + 4                1

y - y1 = m(x - x1)

= y -6 = 3( x + 3)

= y -6 = 3x + 9

= y = 3x + 15

y = 9x -3

Step-by-step explanation:

assuming your trying to get to the equation y = mx+ b you have to set it like

(y - y1) = m(x - x1) first. (and you need the slope)

Find the slope:

y2 - y1             3 - 6              -3                 3

    =         =     =       =     3

x2 - x1            -4 - (-3)            -1                 1

Now we plug in our equation:

( y - 6) = 3( x + 3)

(notice how I changed the ( x - x1) to a ( x + x1 ) because x1 in this case is negative and subtracting a negative is the same as adding)

Now we solve:

( y - 6) = 3( x + 3)

distribute the 3 to x and -3

( y - 6) = 3x -9

now add 6 to both sides to single out the y

y = 9x -3

Hope this helps <3

Also if that's wrong,  I'm sorry and that just means you have to DIVIDE rather then add the 6. In which case, your answer would be y = 0.5x - 1.5 . If you need me to explain I can
