With math super simple i just don’t know how to do it { on the verge of crying }

a)

y = mx + c

m = slope

c = y-intercept

slope = 3

b)

y-intercept = (0, 28.6)

c)

The graph is a line running bottom-left to top-right with a slope of 3. To draw the graph you need to connect two coordinates.

y-intercept = (0, 28.6)

0 = 3x + 28.6

x = - 143/15

x-intercept = (- 143/15, 0)

Draw the axes and label them x and y.

Please don't cry, have an ice-cream.

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.
