Answer:

commission 446.9157$ or 446.92 $ and total pay 1646.92 $

= (12.6/100)×3546.95

= $446.9157

total pay = basic pay + commission

= 1200+446.92

Answer:

(y-24)=-7(x+4)

Step-by-step explanation:

To write the equation of a line we must have a slope and a point. To find the slope we use the slope formula and substitute (x,y) points in it as shown below:

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{24--53}{-4-7}=\frac{24+53}{-4+-7}=\frac{77}{-11}=\frac{-7}{1}=-7$

Now that we have the slope, plug in the slope and choose one point to plug into the point slope formula. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.

(y-24)=-7(x--4)

(y-24)=-7(x+4)
