Tell whether the ordered pair is a solution of the equation. y = x - 5; (6, 11)​
sashaice [31]

Answer:

Not a solution

Step-by-step explanation:

y=x-5

Plug in the point (6,11)

11=6-5

11=1

11≠1

Because the left side of the equation and the right side aren't equal, the ordered pair (6,11) is not a solution to the equation y=x-5.

I hope this helps!

Write the equation of the line that passes through the given points (0,-3) and (-15,-5)
son4ous [18]

Answer:

y=2/15x-3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-5-(-3))/(-15-0)

m=(-5+3)/-15

m=-2/-15

m=2/15

y-y1=m(x-x1)

y-(-3)=2/15(x-0)

y+3=2/15(x)

y+3=2/15x

y=2/15x-3
