Question

what is an accurate method for calculating the slope from a graph? select all that apply. find the rise over the run on the graph. find the run over the rise on the graph. measure the line with a ruler. choose two points and use the slope formula. calculate the horizontal change over the vertical change. calculate the change in y - values over the change in x - values.

Explanation:

Slope is defined as the vertical change (rise) over horizontal change (run), or $\frac{\Delta y}{\Delta x}$ (change in y over change in x). This can be found by identifying rise over run directly on the graph, using two points with the slope formula, or calculating change in y-values over change in x-values. The other options reverse the ratio or use an irrelevant method.

Answer:

• Find the rise over the run on the graph.
• Choose two points and use the slope formula.
• Calculate the change in y-values over the change in x-values.
