Step-by-step explanation:

B

y=2x+4

Step-by-step explanation:

The y-intercept is 4, as the line passes through the y-axis only once, and at (0,4)

The format of a linear graph is y=mx+b where m is the slope and b is the y-intercept.

You can already tell that B is the only one with the y-intercept of 4.

The slope can be calculated quite easily, as we will start from (0,4) and make our way up to the next easily discernible point. The next most easily point seen is (2,8) so we will use the slope equation to find the slope. The equation is more or less like y2-y1  over x2-x1.

The y2 and x2 would be the (2,8) point because that is the second point on the line we are using. The x1 and y1 would be the first point (0,4). Now we will fill in the equation, which will look like 8-4  over 2-0  which will be 4 over 2, simplified to 4/2 and 2/1, being equal to 2.

The slope/m will be equal to 2, so the equation will look like

y=2x+4

Hope this helps!

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.
