Answer:
D
Step-by-step explanation:
because the slope is 7 and y-int is 6
so, u must use y=mx+c
just replace the slope and y-int into that formula

????????.......?????????????????
if we asked questions and somone just ans the question wrongly for free points
therefore you can report the ans and delete the ans..
now a days many people are doing this...
The only way to solve if it is equal to something
assuming that the teacher wanted you to make it equal to zero do
0=-3x^2-21x-54
remember if we can do
xy=0 then assume x and y=0
so factor
0=-3x^2-21x-54
undistribute the -3
0=-3(x^2+7x+18)
remember 0 times anything=0 so
x^2+7x+18 must equal zero
use quadratice formula which is
if you have
ax^2+bx+c=0 then
x=

x^2+7x+18
a=1
b=7
c=18
x=

x=

x=

i=√-1
x=

the zerose would be
x=
