Which equation represents a line with an undefined slope? y = x y = –x y = 0 x = 0

D.

Step-by-step explanation:

We are asked to choose the equation which has an undefined slope.

We know that slope of line will be undefined when the difference between its x-coordinates is 0 as slope is rise over run.

We also know that a vertical line is in form , where, x is any real number.

We also know that slope of a vertical line is undefined as horizontal displacement (run) of a vertical line is 0.

Therefore, the line has an undefined slope.

sss (side, side, side)

sas (side, angle, side)

asa (angle, side, angle)

aas (angle, angle, side)

hl (hypotenuse, leg)

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.
