100 points!!!!!!!!! PLS ASAP HELP!!!!! You’re playing a game where you pick a handful of marbles from a bag. The number of point
s you get depends on the marble’s color. A blue marble is worth 6 points. A green marble is worth 9 points. For each red marble, you lose 12 points. x represents the number of blue marbles, y represents the number of green marbles, and z represents the number of red marbles. Use the menus to write an expression for determining the points earned in a handful.
For a blue marble, you get 6 points. X is the number of blue marbles. For a green marble, you get 9 points. Y is the number of green marbles. For a red marble, you lose twelve points. Z is the number of red marbles.
Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
