Question

Slope help needed- a medal is rewarded
Launch Area: (1, 2)
Point A: (-6, 5)
Point B: (-9, 8)
Point C: (7, -3)

Answer 1

Determine the equation of the line, in standard form, that will get your spacecraft from the Launch Area to Point A.

Determine the equation of the line, in point-slope form, that will get your spacecraft from Point A to Point B.

Determine the equation of the line, in slope-intercept form, that will get your spacecraft from Point B to Point C.

Answer 2

The slope for Launch to A is -3/7
The slope for A to B is 13/3
The slope for B to C is 5/16
I started with these on my own but they didn't look right.

Answer 4

@whalexnuker You did it right for Launch to A but err in calculating slope for A to B and for B to C

Answer 5

for A to B the slope will be -1 and for B to C it will be -11/16

Answer 6

slope between two points,lets say (x1,y1) and (x2,y2) in 2-D is given by
(y2-y1)/(x2-x1)

Answer 7

Huh? "but err"?
y2-y1/x2-x1 = 8-5/-9-(-6) = 3/-3 = -1
A: -6, 5
B: -9, 8

Are you sure it's -1? Because in the beginning, I added 6 since two negatives make a positive

Answer 8

y2-y1/x2-x1 = -3-8/7-(-9) = -11/16
Point B: (-9, 8)
Point C: (7, -3)
Still, are you sure? Because I added (again) because two positives make a negative

Answer 9

Hey adding two negative integers will always give negative integer.
Multiplying two negative values makes the product positive

Answer 10

Yup I am damn sure about it..
Don't u get it?

Answer 11

@whalexnuker ??

Answer 12

uh, no. Adding two negatives give you a positive e_e @quantun
