    y = slope x + intercept

    Y=mx+b where m is the slope and b is the intercept

    With the above knowledge, you can solve this by inspection.

    Use the problem as an example. What is m the slope. You know it is the coefficient of x!

    there is a number in the place for "slope"; what number is that?

    -4, -10 does this make sense?

    y = -2/3 x + -12 y = slope x + intercept

    this question is designed to get you to become familiar with the form of the equation; not any particular points on it

    slope intercept uses the slope and the intercept as part of the equation itself

    When the line equation is in slope intercept form, as is the one you are working with, the coefficient of x is the slope, the constant is the intercept. They are there in your equation, just pick them out.

    So what radar is saying is that you don't need to do anything. The answer is right in front of you. Many times in math we complicate things too much and many times the answer is right in front of us.

    So in this case m is the slope. so what is M? Then what is B since B is the y intercept?

    Maybe this will help y= (m)x + (b)
