Which of the following is an equation of the line a graphed in the xy plane that passes through the point (-1, 3.5) and is perpendicular to line b whose equation is x + 4.5=0

y=3.5

Step-by-step explanation:

To find the slope, convert the standard form of the equation into slope intercept form, y=mx+b.

x+4.5=0

x=-4.5

The slope is 0. To create a perpendicular line, it must y= a value which will cross (-1. 3.5).

y=3.5

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

pls mark as brainliest

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
