How do you find the m and b in the problem y=-x+1?

1 answer:

6 0

In Y=mx+b:

m=slope. That is found by using this formula y2-y1/x2-x1

b=y-intercept. That's found by finding slope, m, and substituting that into y=(m)x+b. Then you have to solve for b and that'll be your y-intercept.

Scale of a model airplane to the actual airplane is 1 inch equals 10 feet. How many times longer the actual plane is than the mo

WINSTONCH [101]

Answer:

120 times

Step-by-step explanation:

If we want to find a qunatity is how many times as other quantity, we have to divide the large one by the small one (remember, same units).

Let's make both into inches.

We have 1 inch [model]

also

10 feet * 12 = 120 inches

Thus, we can say:

120/1 = 120 times

So, Actual Plane is 120 times than model airplane
