Graph a line that contains the point (6, -5) and has a slope of -2/3.
Lapatulllka [165]

We know that the equation of the line is in the form y=-\frac{2}{3}x+b. To find b, we can use the fact that (6,-5) lies on the line, meaning that both sides of the equation are equal when x=6 and y=-5.

-5=-\frac{2}{3}(6)+b\\-5=-4+b\\b=-1

Hence, the equation of the line is y=-\frac{2}{3}x-1, and its graph looks something like follows.

6,500 acres of a 41,000 acre forest burned in a fire. what percentage of forest was damaged?​
Tems11 [23]

Answer:

15.85%

Step-by-step explanation:

Given:

Acres damaged (burned) = 6,500 acres

Acres in total forest = 41,000 acres

Hence the amount of damaged forest as a fraction of the total forest,

= \frac{6500}{41000} = \frac{13}{82}

expressed as percentage = \frac{13}{82} x 100% = 15.85%
