Linear Equations Quiz

What is the formula to find the slope of a linear equation?

• slope = (y1 + y2) / (x1 + x2)

• slope = (y1 - y2) / (x1 - x2)

• slope = (y2 - y1) / (x2 - x1)

• slope = (y2 - y1) * (x2 - x1)

Explain how to graph a linear equation using its slope and y-intercept

• Plot the slope on the x-axis and the y-intercept on the y-axis.

• Start by drawing a circle at the y-intercept and then connect it to the slope.

• Use the slope to determine the x-intercept and then plot the line.

• Plot the y-intercept on the y-axis and use the slope to find the next point to draw the line.
