This week in math 10 we learned about linear relations. This week we learned a bit more about the X and Y intercepts.

•  We learned hat when graphing there is a dependent variable (y) and an independent variable (x)
• We also learned how to solve for the x and y intercepts
• When solving for the x intercept y = 0
• When solving for the y intercept x = 0

Example:

How to solve for the x or y intercepts:

1. If solving for the x intercept replace all y’s with zero. If solving for the y intercept replace all x’s with zero. In this case we will be solving for the x intercept
2. next you need to isolate the variable so you + or –  the constant to cancel it out. What you do to one side of the = sign you do to the other so in this case you add 33 to both sides of the equation.
3. Next to isolate the x you divide both sides of the equation by the coefficient (number beside the variable) to get the value of x.
