Find the slope first
slope=(2-1)/(-1+3)=1/4=.25

now use the slope and either point to write in point slope form
y-1=.25(x-2)
y-1=¼x-½

to rationalize all the denominators multiply by the last common multiple, here we get 4
4y-4=x-2

then put in the correct order

x-4y=-2

Based on its degree, what kind of polynomial is this? h(x) = 4x^4 + 2x - 5

cestrela7 [59]

Answer:

Quartic

Step-by-step explanation:

Given

$h(x) = 4x^4 + 2x - 5$

Required

Name the polynomial

The question required that the polynomial be named based on its degree.

This implies that, we name the polynomial based on the highest power of x

Highest power of x = 4

When the highest power of x in a polynomial is 4, such polynomial is a quartic polynomial.

Hence, by degree; the polynomial is quartic
