2. Which equation in standard form has a graph that passes through the point (-5,8) and has a
atroni [7]

Answer:

a

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 )

Here m = - \frac{1}{5}, thus

y = - \frac{1}{5} x + c ← is the partial equation

To find c substitute (- 5, 8) into the partial equation

8 = 1 + c ⇒ c = 8 - 1 = 7

y = - \frac{1}{5} x + 7 ← in slope- intercept form

Multiply through by 5

5y = - x + 35 ( add x to both sides )

x + 5y = 35 ← in standard form → a

A store owner pays $1,200 each month for rent to pay the clerk who works in the store $15 an hour the clerk works 60 hours each
Anna11 [10]
So for this problem the equation would be y=15x+1200
x, being the number of hours the store clerk works is 60. You then multiply 15x60 and get 900. 900 hours + 1200 rent is 2100 total. So A. :)
