Which statements accurately describe how to determine the y-intercept and the slope from the graph below?

On a coordinate plane, a line goes through points (0, negative 6) and (3, 0).
To find the y-intercept, begin at the origin and move horizontally to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction.

summary

Step-by-step explanation:

Answer: Choice C

To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = (y2-y1)/(x2-x1)

============================================

Explanation:

The y intercept is where the graph crosses the vertical y axis. So that's why we move vertically from the origin to get to the graph.

The slope is calculated as the difference of y values over the difference in x values. We subtract in the same order for both. In other words,

slope = rise/run = (change in y)/(change in x)

Positive slope means the line goes uphill when you move from left to right. Negative slope means the line goes downhill when you move from left to right.
