So first you would substitute x for four, so it would say Y=12-6(4)

Then you would multiply 6 and 4

Then you would subtract 12 and 24

You should get Y= -12

Y=12-6 times 4
y=12-24
y=-12

Multiply the top equation by 6 and the bottom equation by 7. You will cancel x first by doing this and solve for y. You should get y=-1.
Substitute in y for either original equation.
You should get x=1.
Solution is (1,-1).

Purchasing the correctly sized BMX bike is based on the height of the rider. In order to fit a customer, the salesman can use th

Archy [21]

Answer:

(a) 1 inch of rider ⇒ 0.29 inches of frame

Step-by-step explanation:

The "slope" in the equation is the coefficient of the independent variable. Here, that variable is "h", and its coefficient is 0.29. That is, the height of the rider is multiplied by 0.29 (and a constant is added) in order to find the height of the frame.

The meaning of the value 0.29 is that a 1 inch increase in the rider's height should result in a 0.29 inch increase in the height of the frame of the bike.

The question asks for an explanation of the slope, not its function in the equation. That is why we have chosen the first answer.
