Write an equation in slope-intercept form of the line that passes through (-1,4) and (0,2)

y = -2x + 39

Step-by-step explanation:

2 - 4 = -2 (with negative numbers graphs help a lot more)

0 - -1 (since there are two negatives together you change both of the signs to their opposite so they both become positive)

0 + 1 = 1

-2/1 = -2 because a negative divided by a positive is a negative

I found the y-intercept by substituting one of the points into y=mx+b

the answer is y= -2x+2

Step-by-step explanation:

I hope it's right

do i do it on a graph?

step-by-step explanation:

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.
