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.

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
