Answer:
y = - x - 11
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 10, - 7) and (x₂, y₂ ) = (- 5, - 9)
m = = - , hence
y = - x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (- 5, - 9 ), then
- 9 = 2 + c ⇒ c = - 9 - 2 = - 11
y = - x - 11 ← in slope-intercept form
Answer:
It's the third option
Step-by-step explanation:
the domain is all the x values
Answer:
21÷-3=-7
I dont know what all those extra boxes are for but I hope I helped a little
We don’t know which one is the hypotenuse. So if we were to plug it into the Pythagorean theorem, we wouldn’t know where to put it. Two possible answers:
8 squared (copy pasting the symbol here is an inconvenience) + b squared = 10 squared which is 6m after solving.
Or you could say 8 squared + 10 squared = c squared. Solving for C would get us 12.8m as our second possibility.
A and C are false.
A should be -9 < -4
C should be -8 < -5
In both cases, the number on the right is less negative than the number on the left, so they are larger.
