What is an equation of the line that passes through the point (4,-6) and has a slope of -3

Step-by-step explanation:

In order to find the equation of a line when one point and a slope is given , we will use the formula:

where m is the slope.

m =

substituting into the formula , we have :

subtract 6 from both sides

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480
