What is the equation of the following line? Be sure to scroll down first to see

Gnom [1K]

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (2, - 8) ← 2 points on the line

m = $\frac{-8-0}{2-0}$ = $\frac{-8}{2}$ = - 4

The line crosses the y- axis at (0, 0) ⇒ c = 0 , then

y = - 4x + c , that is

y = - 4x → A

You buy a container of cat litter for $11.50 and a bag of cat food for x dollars. The total purchase is $16.80, which includes 5

Anni [7]

let cat food = x

total plus 5% = 105% = 1.05

1.05 * (11.50 + X) = 16.80

12.075 + 1.05x = 16.80

1.05x = 16.80-12.075

1.05x = 4.725

x = 4.725 / 1.05

x= 4.50

the cat food cost $4.50

11.50 +4.50 = 16.00

16.00 * 0.05 = 0.80

16.00 + 0.80 = 16.80
