Write an equation in point-slope form for the line through the given point that has the given slope.

(5, –8); m = –3

y=mx+b is the formula. So -8=-3x+5 would be the answer..

since (x,y) just substitute these numbers you have it into the formulas... Take y from (5,-8) and place it into y=mx+b. Next take the slope which is -3. And then since its a postive number we add are x from (x,y). -8=-3x+5. We also add x next to the slope (-3) becuase we are trying to solve for x. And we always put it next to the slope. Hope this helps!

Step-by-step explanation:

hello :

note :

Use the point-slope formula.

y - y_1 = m(x - x_1)    you have : m=-3  and x_1 = 5  and  y_1 = -8

an equation in the point-slope is : y +8 = m(x - 5)  

9x

the answer is 11.2 (i know i’m late)
