Explanation:
Y2 - Y1
X2 - X1
3 - 1
2 - 1
= 2
y - Y1 = m (x - X1)
y - 1 = 2(x - 1) --- IN POINT SLOPE FORM
y - 1 = 2x - 2
+ 1 + 1
y = 2x - 1 --- IN SLOPE INTERCEPT FORM
QUESTION 12:
Slope intercept form -
- y = mx + b
- m represents the slope
- b represents the y - intercept AKA the starting point
- When the slope is negative, you go down
- When the slope is positive, you go up
ABOUT PROBLEM:
- Since the slope is negative, you go down 4, right 3, but start from the 2 then start doing the slope
- You have to put 2 on the y - line because it's the y - intercept AKA starting point
y = -4/3x + 2
