What is the slope of the line that goes through the points (42, 16) and (40, 36)?

Find the x-intercept of the line. 4x+6y=14.1

You will find the y-intercept on the next question.

Given the equation  $y=-\frac{3}{5}x-2$     . What is the y-intercept? On the next question I will ask you the slope.

Given the equation  $y=-\frac{3}{5}x-2$     . What is the slope of the line?

 $15x+12=-3y+6$  

Find the y-intercept of the given line.

 $15x+12=-3y+6$  

Find the slope of the given line.

Write the equation of the line that goes through (-3,-5) and has a slope of  $\frac{3}{2}$  in point-slope form. 

 $3y-x\le-6$  

Choose all of the ordered pairs that are solutions to the inequality,

Jim’s fundraiser BBQ needs to make at least $1000 in sales on Saturday. He sells hot dogs for $2 each and hamburgers for $3 each, and he wants to sell at least twice as many hamburgers as hot dogs. He brought 300 hot dogs and 800 hamburgers to sell.

The graph shows the feasible region, where x represents the number of hot dogs sold and y represents the number of hamburgers sold.

Which ordered pairs meet all the constraints for a successful fundraiser and make sense in context of the situation?
