Find an equation of the line that pases (8,17) and is perpendicular to the line x+2y=2

y = 2x + 1

Step-by-step explanation:

The equation of line is given in this format:

y = mx + b

Where m is the slope and b is the y-intercept

Now, let's take this equation and put it in this format:

Line perpendicular to this will have slope that is "negative reciprocal" of this. Which means that it will be "flipped" and negative of this line's slope.

The slope of this line is  and thus perpendicular line has slope 2

So perpendicular line will have equation:

y = mx + b

y = 2x + b

Passes through the point (8,17), so we plug in x = 8 and y = 17 and get b:

So, the equation is:

y = 2x + 1

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.
