Question

Find two points for each labeled line in the graph below. Then use those two sets of coordinate points to help you find the slope and use whichever method for finding equations that you prefer to find the equation of each line listed. You only need to write the equation of each line for your answer. Remember, you must first put the equations in slope-intercept form. Label your answers m and b to represent the slope and y-intercept.

B:
C:
D:

Answer 1

???

Explanation:

wheres y

Answer 2

the equation to find slope is (y2-y1)/(x2-x1)

A: (-4,1) (0,3) (for all of these except for the last one, i included the y-intercept as one of the points)

3-1/0-(-4)

2/4

m=1/2

y= 1/2x +3

B: (0,-1) (3,1)

3-0/1-(-1)

m=3/2

y= 3/2x -1

C: (0,-3) ( 6,-1)

-1 -(-3) / 6-0

2/6

m= 1/3

y = 1/3x -3

D: (3,-3) (6,0)

0 -(-3) / 6-3

3/3

1

m= 1

y -y1 = m (x - x1) (this is point-slope form, plugging in the slope and a point on the line, and then solving it will give you slope-intercept form)

y - 0 = 1(x -6)

y = 1x -6
