Please help! Last time I made it and gave away 50 points and got the wrong answer :( include answers for a b and c

Step-by-step explanation:

Choose two points from the graph:

(x1, y1) = (1, 10)

(x2, y2) = (2, 20)

Substitute these values into the slope formula:

m = (y2 - y1)/(x2 - x1)

m = (20 - 10) / (2 - 1) = 10/1 = 10

Slope = 10

where:

y = distance that a snail crawls (in inches)

x = time in minutes that a snail crawls

The slope = 10 is the rate of change; it represents an increase of 10 inches   in distance that a snail crawls for every minute that passes.

To determine how long will it take for the snail to crawl 85 inches, substitute its value into the equation to solve for x:

y = 10x

85 = 10x

Divide both sides by 10:

x = 8.5

Therefore, it will take a snail 8.5 minutes to crawl for a distance of 85 inches.

is means division by fractions

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
