Find the slope and the y-intercept of the line. $$3 x+2 y=10$$
Check whether \((0,0)\) is a solution. Then sketch the graph of the inequality. $$ x>-2 $$
In the last quarter of a high school football game, your team is behind by 21 points. A field goal is 3 points and a touchdown (with the point-after- touchdown) is 7 points. Let \(x\) represent the number of field goals scored. Let \(y\) represent the number of touchdowns scored. a. Write and graph an inequality that models the different numbers of field goals and touchdowns your team could score and still not win or tie. (Assume the other team scores no more points.) b. Does every point on the graph represent a solution of the real-life problem? Give examples to support your answer.
Find the slope of the graph of the linear function \(f\). $$f(2)=-1, f(5)=5$$
Check whether \((0,0)\) is a solution. Then sketch the graph of the inequality. $$ x+y \geq-1 $$
