Slope point to y intercept form
This week in math 10 we learned about 3 different forms of equations. Today I will be changing point slope form into y-intercept form.
(1) General form: ex. 2x + 3y + 8 = 0
(2) y – intercept form: ex. y = 2x + 5
(3) Point slope form: ex. (9,3), 4 –> 4(x-9) = y – 3
Step 1 – Distribute the number that is in front of the brackets into all of the numbers inside the brackets.
Step 2 – You want to get y alone, and in order to isolate the y variable you need to flip the number beside the y to the other side of the equal sign. (Remember whenever bring any number to the other side you must change the sign.)
Step 3 – If there are 2 constants add or subtract them together.
