Write the equation of the line that goes through the point (-2,3) and has a slope of -4​
Scilla [17]

Answer:

y=-4x-5

Step-by-step explanation:

Use the equation of the line formula, y=mx+b

since we know that the slope is -4, we just have to find b

plug the points into the equation, y=-4x+b

(3)=-4(-2)+b

simplify

3=8+b

subtract 8 from both sides

b=-5

plug b into the equation

y=-4x-5

Mrs .Walker saves 1/3 of her money from her part time job. If 2/5 of mrs.Walker salary from her part time job is 78.00,how much
lorasvet [3.4K]

Answer:

The money which Mrs. Walker saves each week is $ 65 .

Step-by-step explanation:

Given as :

The part of money which Mrs. walker saves from part time job = \frac{1}{3} of her total earning

The value of  \frac{2}{5} part of her salary = $ 78.00

Let The total earning from part time job = $ x

So, The value of  \frac{2}{5} of total earning = $ 78.00

Or,  \frac{2}{5} × x = 78.00

Or, x = \frac{78\times 5}{2}

∴ x = 39 × 5

I.e x = 195

So, her total earning from part time job = x = $ 195

Now ∵ The part of money which Mrs. walker saves from part time job = \frac{1}{3} of her total earning

So,  The part of money which Mrs. walker saves from part time job = \frac{1}{3} × 195

Or, The part of money which Mrs. walker saves from part time job = \frac{195}{3}

∴ The part of money which Mrs. walker saves from part time job = $ 65

Hence The money which Mrs. Walker saves each week is $ 65 . Answer
