At the beginning of the 7th grade, Martin was 50 inches tall. At the beginning of his 8th grade year, Martin was 58 inches tall. What was his percent of change from his 7th grade year to his 8th grade year?

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

the answer is 15.50 for one mile

b) is slope: 0   y- intercept 15.5
