Choose the equation below that represents the line passing through the point (2, −5) with a slope of −3

For this case we have that the point-slope equation of a line is given by:

Where:

m: It's the slope

It is a point

We have to:

Substituting:

ANSWER

or

EXPLANATION

The equation is calculated using the formula,

where m=-3 is the slope and

We substitute the the values to get:

Expand

This is the slope-intercept form.

Or in standard form;

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.
