Put all of the equations in slope-intercept form y = mx + b
The graph has a positive slope and a negative y-intercept.


A. 2x - 3y =-9
-3y = - 2x - 9
y = 2/3 x + 3 Positive slope, positive y-intercept

B. y = 3x - 2 Positive slope, negative y-intercept

C. y = -10 Horizontal line: zero slope, negative y-intercept

D. -4x + 2y = -6
2y = 4x - 6
y = 2x - 3 Positive slope, negative y-intercept

Letters B & D

The line given shows a positive slope and has a negative y intercept.

A:
2x - 3y = -9
2x + 9 = 3y
/3 /3 /3
2/3x + 3 = Y

A is not correct. It doesn't meet the description (not a negative y intercept)

B:
correct because it meets the description (positive slope, - y intercept)

C:
not correct. It doesn't meet the description. (not a positive slope)

D:
-4x + 2y = -6
-4x + 6 = -2y
/-2 /-2 /-2
2x - 3 = y

D is correct because it meets the description (positive slope, negative y-int.)

Hope I helped lol
Answers are D and B.
