Write an equation of the line with the given slope and y-intercept.

Undefined slope; (-4, 10)
Question 9 options:

x = -4

10x - 4y = 0

-4x + 10y = 0

y = 10
Question 10 (1 point)
Write the slope-intercept form of the equation for the line passing through the given pair of points.

(-1, -9) and (10, -9)
Question 10 options:

10x - 1y = 0

x = -1

-1x + 10y = 0

y = -9

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.

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

he answer is x=1x3 because x=1 to x=3
