Compare the two sets of equations below. One set is presented in slope-intercept form , and the other set is not. How can you tell if an equation is written in slope-intercept form? One way to determine the slope of a line, given its equation, is to change the equation to slope-intercept form, and then identify the coefficient of the x term. The coefficient of the x term is the slope of the line. To write an equation in slope-intercept form, you must solve the equation for y.

Enter a problem Hope that helps! You'll be able to enter math problems once our session is over. Algebra Examples Step-by-Step Examples. Check if the function rule is linear. To find if the table follows a function rule, check to see if the values follow the linear form.
The equation of a line expresses a relationship between x and y values on the coordinate plane. Since, as we just wrote, every linear equation is a relationship of x and y values, we can create a table of values for any line. In other words, a table of values is simply some of the points that are on the line. So, to create a table of values for a line, just pick a set of x values, substitute them into the equation and evaluate to get the y values. An Optional step, if you want, you can omit the middle column from your table, since the table of values is really just the x and y pairs. We used the middle column simply to help us get the y values.
