How do you solve for a y and x intercept?

For a y-intercept, set in your equation. Remember that a y-intercept intercepts the y-axis, which is found at . Thus, setting will give you the place where your equation intercepts the y-axis.

For an x-intercept, do the opposite, set . This is because the x-axis is found at . Similar to the y-intercept, this will find you the point where your equation intercepts the x-axis.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
