You first need to isolate the y
4x+9y=-108
9y=-4x-108 (subtract 4x from both sides)
y=-4/9x-12 (divide both sides by 9)
Then, by using the y=mx+b form, we can tell that the y-intercept is -12 so A

Hope this helps

point slope:
for opint (x1,y1) and slope m
y-y1=m(x-x1)

so example
(1,2) and slope 3
y-2=3(x-1)

slope intercept
y=mx+b
m=slope
b=y intercept
if slope is 2 and y intercept is 3
y=2x+3

standard form
Ax+By=C
easies of all, just put randome numbers

2x+3y=4
A=2
B=3
C=4

Linda has scored 84, 93, 91, and 60 on her previous four tests. What score does she need on her next test so that her average (m

vovikov84 [41]

Answer:

She needs to score 82

Step-by-step explanation:

Mean of five test scores = 82

Let the score she got in fifth test = x

$\frac{84+93+91+60+x}{5}=82\\\\\frac{328+x}{5}=82\\\\328+x=82*5\\\\328+x=410\\\\x=410-328\\\\x=82$
