Question

What is the slope of these two points: (3,6) (1,-2) a) Find the y intercept and write the equation in slope intercept form. b) Identify the slope and the y intercept. c) Graph it!

Answer 1

SOLUTION:

Case: Equation of line

Method:

Slope-intercept form:

y= mx + b

when (x,y) is (3,6)

6 = m(3) + b

6= 3m + b...........(1)

when (x,y) is (1,-2)

-2 = m(3) + b

6= 3m + b...........(1)
