Answer:
y=x+12
Step-by-step explanation:
Well the slope is -4/-4 =1
We plug it into the formula, y=mx+b, but m=1
So it is y=1x+b
We know the points, so we plug y and x in which is:
-4=-4*4+b
-4=-16+b
b=12
So the point slope form of that is y=x+12
Answer:
y = - x - 2
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 ) = (- 5, 4) and (x₂, y₂ ) = (5, - 8)
m = = = -
y = - x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (5, - 8), then
- 8 = - 6 + c ⇒ c = - 8 + 6 = - 2
y = - x - 2 ← is the equation of the line
Plug in x = 6 into the function
<span>f(6) = 6² + 5(6) - 9
</span>f(6) = 36 + 30 - 9
f(6) = 57
Answer:
(5+7)/2 = 6
Step-by-step explanation:
Answer:
Kalpana = 49
Abhilasha = 77
Gouri = 16
Step-by-step explanation:
You can write this as an equation, where Kalpana is x, to make it easier to understand.
Gouri + 33 = x
Gouri = x - 33
Abhilasha - 28 = x
Abhilasha = x + 28
Now just plug in 49.
49 - 33 = 16
49 + 28 = 77
