What is the slope and y-intercept for the line represented by this equation? – 7x + 3y = – 9
a. b.
c. d.

To determine the slope and y - intercept of the line represented by -7x + 3y = -9, convert the equation first to slope - intercept form which is generally expressed as,
 
                                       y = mx + b

where m is the slope and b is the y-intercept.
               
                                       3y = 7x - 9

Dividing both sides of the equation by 3,
 
                                       y = (7/3) x - 3

Thus, the slope is 7/3 and the y-intercept is -3. 

The answer is 30 minutes to an hour
