Answer:
y = 2x^2 - 12x + 27
Step-by-step explanation:
<u>Step 1: Distribute the power</u>
y = 2(x - 3)² + 9
y = 2(x^2 - 6x + 9) + 9
y = 2x^2 - 12x + 18 + 9
y = 2x^2 - 12x + 27
Answer: y = 2x^2 - 12x + 27
the equation of a line in point-slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
to calculate m use the gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 4, - 1) and (x₂, y₂) = (1 1/2, 2 )
m = 
= 
= 
using (a, b) = (- 4, - 1), then
y + 1 = (x + 4)
Answer:
3x-2y=-4 is the equation of the slope intercept line.
Step-by-step explanation:
The passing through point (4,8)=(x1,y1)
Slope(m)=3/2
the equation is
or (y-y1)=m(x-x1)
or (y-8)=3/2(x-4)
or 2y-16=3x-12
or 2y-3x=16-12
or 2y-3x=4
or -(3x+2y)=4
or 3x-2y=-4
This is the Final equation of that line..
