A line contains the points (-7, -2) and (-9, y). Find the value of y so that the line has a slope of
−3/5

Respuesta :

Answer:

x1=x

x2=3

y1=5

Y2=9

And dy/dx=2

therefore, the solution for x is

2=(9−3)/(5−x)=6/(5−x)

2(5−x)=6

Dividing both sides by the coefficient of (5-x)

5−x=3

then x=5−3=2

Therefore x=2

to solve for y

3=(y−(−5))/(4−(−3))=(y+5)/(4+3)

3=(y+5)/7

Multiplying both sides by 7

21=y+5

y=21−5

y=16

Therefore

Answer:

-0.8

Step-by-step explanation:

use the slope intercept form
