The correct answer is: slope-intercept form

Step-by-step explanation:

Step 1

Recall that the first step in solving a system of linear equations using the substitution method is to solve one of the equations for one of its variables.

Of all the forms listed, only the slope-intercept form of an equation automatically has one of its variables solved-for (point-intercept form is not a real form). This means that if one of the equations in a system is already in slope-intercept form, then the first step can be skipped in using the substitution method.

Step 2

Match your solution to the correct answer choice.

Answer choice C is the only answer choice that identifies the form of linear equation that is the simplest to start when using the substitution method. Select answer choice C and move on to the next question.
