4b.) write an equation using point-slope form with a slope of 2.3 and goes
through the point: (4.5, -3.2)

Step-by-step explanation:

So the point-slope formula looks like this:

= any y point on the line

= any x point on the line

= the slope

And hey, look, we're already given all that information!

So we can just plug those values into the equation:

(*note: It's a +3.2 because 3.2 was negative in the first place, and -(-x) = +x)

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
