Answer:

<h3>y=-3x+15</h3>

Step-by-step explanation:

$m=-3\\\\(4,3)=(x_1,y_1)\\\\$

Substitute values into point slope form

$y-y_1=m(x-x_1)\\\\y -3=-3(x -4)\\\\y-3=-3x +12\\\\y=-3x+12+3\\\\y=-3x+15$

What is the answer for this:

cricket20 [7]

Step-by-step explanation:

Okay! To do this you need to have x on one side (isolate the variable) and also combine like terms. Like terms are terms with the same exponent and variable, like 8x and 6x.

8x+1=-6x-2 To combine like terms here we have to move -6x to the other side of the equation by adding it (using inverse operations). 8x+6x=14x

14x+1=-2 now subtract 1 from both sides.

14x=-3

Divide both sides by 14 and x=-3/14
