Write a point-slope form of an equation for a horizontal line that passes through (5, -9)

See below.

Step-by-step explanation:

Point-slope form is y - y1 = m(x - x1) where m = slope and (x1,y1) is a point on the line.

Because the line is horizontal the slope m = 0  so the answer is:-

y - (-9) = 0(x - 5)

or y + 9 = 0(x - 5)   which simplifies to:

y + 9 = 0

giving  y = -9.

the answer is b.)

< 1=< 2

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
