Intermediate Algebra

Must show work.

1.)  Determine whether (-2, 3) is a solution of the equation x+3y=11

2.) True or false: To find a y-intercept, let x=0 and solve for y.

3.) Explain the difference between a zero slope and undefined slope.

4.) Solve the inequality.  Write the solution set using interval notation and graph the solution set on a number line: 4x-5>7x+10

5.) Find the intercepts: 4x+2y=9

6.) Given the points (-2, 1) and (3, -4): Find the slope of the line through the points.

7.) Solve the compound inequality.  Write the solution set using interval notation and graph the solution set on a number line: -11 less than or equal to 4x+1<17

8.)   Given the points (-2, 1) and (3, -4): Write an equation in point-slope form of the line through the points.

9.)   Given the points (-2, 1) and (3, -4): Convert the equation to slope-intercept form.

10.)  Given the points (-2, 1) and (3, -4): Convert the equation to standard form.
