PLEASE ANSWER THIS I NEED HELP RNNN :)

Step-by-step explanation:

1. change in y over change in x.

  =

  This becomes your slope.

   the y-intercept is 100 because at x = 0, y= 100.

   So plug these values into y = mx + b and you get y = x + 100.

2. If the line starts at x = 0, then if you want to get a value for 2 minutes prior           you have to use -2 because 0 - 2 = -2.

   y = (-2) + 100

   Set it equal to zero and solve algebraically. The answer should be   100.56.

3. If we want to see how many minutes it takes to get to an altitude of 0, we have to make y = 0  and solve for x. This is because we know that y will be 0 but we don't know how long it takes.

    0 = x + 100

    Solve algebraically and you should get an answer around 357.

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
