Rewrite
(7m-3)^2 as (7m-3) (7m-3) (7m-3) (7m-3)
Expand using foil method
7m(7m)+7m. -3 -3 (7m) -3. -3
Simplify 49m^2-42m+9
Use the form ax^2+bx=c to find the values of a,b,and c
a=49, b=-42, c=9
Consider the vertex form of a parabola
a (x+d)^2 +e
Find d
d=-3/7
Answer:
y = 2x
Step-by-step explanation:
calculate the slope of AB using the slope formula
m =
with (x₁, y₁ ) = A (8, 3) and (x₂, y₂ ) = B (12, 1 )
= = = -
given a line with slope m then the slope of a line perpendicular to it is
= - = - = 2
the equation of a line passing through the origin (0, 0 ) is
y = mx
here m = 2 , then
y = 2x ← equation of perpendicular line
