7/5. Slope is rise over run. From -3 to 4, rise is 7. It goes 5 to the right from -8 to -3.

Need help with this!!

Answer:

below

Step-by-step explanation:

1) slope = rise / run

2 coordinates are (-4, 0), (0, 2).

2 - 0 = 2

0 -- 4 = 4

2 / 4 = 1/2 so the slope is 0.5 or ½

2) it crosses the y axis at the average of the origin and 4.

4 + 0 = 4 / 2 = 2 so y intercept is 2.

3) in y= mx + b form

f(x) = ½x + 2, or, f(x) = 0.5x + 2

How high is a 30-story building

Sliva [168]

Not all 30-story buildings are the same height. Depends on how tall the ceiling is on each floor. But usually it is around 300 feet

If A= (7,9) and B= (3,12) what is the length of AB?

MissTica

The length can be found using the Pythagorean Theorem...

c^2=a^2+b^2 and in this case:

d^2=(dx^2)+(dy^2)

d^2=(3-7)^2+(12-9)^2

d^2=-4^2+3^2

d^2=16+9

d^2=25

d=5

So the length of AB=5 units.
