(a) write a linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission. (b) explain your answer to part 1a. 2. a line goes through the points (8, 9) and (-2, 4). (a) what is the slope of the line? show your work (b) write the equation of the line in point-slope form. show your work (c) write the equation of the line in slope-intercept form. show your work. for this question, refer to the system of inequalities below. be sure to clearly answer all 4 parts! {█(y≤ -3x+5@8x-4y< 24)┤ graph the system of inequalities name a point (as an ordered pair) that is a solution to both inequalities. name a point (as an ordered pair) that is not a solution to either inequality. name a point (as an ordered pair) that is a solution to the first inequality, but not the second.
