Write an equation for the line.<br><br> with a slope of - 3/4 and a y-intercept of -3 ________

HELP 50 POINTS need this so my mom doesn't yell at me

Citrus2011 [14]

Answer:

1. so (1,-10) passes both equations

2. The dotted line is the line y > -x+3 and the solid line is y ≤ 2x -2

3. The solid line is the line y≤ -x+2 and the other solid line is y ≤ -3x +2

Step-by-step explanation:

y≤x-5

y≤-x-4

Substitute the points in and see if they work

(1,10)

10 ≤1-5 10 ≤-4 False

10 ≤-1-4 10 ≤-5 False

so (1,10) Fails both equations

(-1,10)

10 ≤-1-5 10 ≤-6 False

10 ≤1-4 10 ≤-3 False

so (-1,10) Fails both equations

(10,1)

1 ≤10-5 1 ≤5 True

1 ≤-10-4 1 ≤-14 False

so (10,1) Fails one equations

(1,-10)

-10 ≤1-5 -10 ≤-4 True

-10 ≤-1-4 -10 ≤-5 True

so (1,-10) passes both equations

2. The dotted line is the line y > -x+3 and the solid line is y ≤ 2x -2

The dotted line means less than or greater than. It is shaded above so it is greater than. The y intercept is 3. The slope is down 1 to the right one (-1/1) y> -x+3

The solid line means greater than or equal to or less than or equal to. Since it is shaded below it means less than or equal to. The y intercept is -2. The slope is up 2 to the right one (2/1) y≥ 2x-2

3. The solid line is the line y≤ -x+2 and the other solid line is y ≤ -3x +2

The solid line means greater than or equal to or less than or equal to. It is shaded below so it is less than or equal. The y intercept is 2. The slope is down 1 to the right one (-1/1) y≤ -x+2

The solid line means greater than or equal to or less than or equal to. Since it is shaded below it means less than or equal to. The y intercept is 2. The slope is down 3 to the right one (-3/1) y ≤ -3x +2

Plane A was flying at an altitude of 8 km and Plane B was flying at an altitude of 700 dam. Which plane was flying at a greater

Evgen [1.6K]

Answer:

Step-by-step explanation:

1 km= 1000 m

1 dam= 10 m

8 km= 8000m

700 dam = 7000m

so Plane A
