Answer:
y = 2x - 6
Step-by-step explanation:
(3,0)
y = 2x + 5
m = 2
y - y₁ = m(x - x₁)
y - (0) = (2)(x - (3))
y = 2(x - 3)
y = 2x - 6
Use the FOIL (first, outside, inside, last) to expand the terms in the brackets.
(w - 7)(w + 4)
first: w × w = w²
outside: w × 4 = 4w
inside: -7 × w = -7w
last: -7 × 4 = -28
Now you add all the terms together to get:
w² + 4w - 7w - 28
This simplifies to give you:
w² - 3w - 28
Hope that helps! :)
You might need to use the distance formula
for the distance betwen (x1,y1) and (x2,y2) is

so find disance between (-3,1) and (-1,3)
and (-1,3) and (3,1)
so
if we did input them
we would get

which is the peirmiter
Answer:
