M the table below represents a function. which of the following equations could be its function rule? x y 0 -2 1 0 3 4 -2 -6 y = x - 2 y = 3x - 3 y = -2x y = 2x - 2

slope-intercept form of a line y=mx+b.

where m= slope and b=y-intercept.

y-intercept is a point at which the the graph of the line intersect at y-axis. at y-axis x is 0.

from the given data, notice that y=-2 for x=0.

so, b=-2.

now we just need to find the value of m to get the equation.

let's use any point from the data and plug into the above equation .

so, by using (1, 0), substitute x=1, y=0 and b=-2 in y=mx+b. so,

0=m*1 -2

0=m-2

0+2=m-2+2 add 2 to each sides.

2=m.

so, the equation will be y=2x-2.

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.
