left parenthesis negative 7 comma space 13 right parenthesis semicolon space s l o p e space equals space minus 2

y - 13 = -2(x+7)

Step-by-step explanation:

Given

Coordinate point (-7, 13)

Slope m = -2

We can express the euation of the line in point slope form as shown;

The point slope form of the equation is expressed as;

y - y0 = m(x-x0)

x0 = -7, y0 = 13 and m = -2

Substitute;

y - 13 = -2(x-(-7))

y - 13 = -2(x+7)

Hence the required equation in point- slope form is y - 13 = -2(x+7)

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.
