Remember
we can do anything to an equation as long as we do it to both sides
try to isolate the variable
you have 2 types
x+b=c
x/b=c
fior the first type, minus b from both sides to get
x=c-b
for the second, multiply both sides by b to get rid of the fraction to get
x=cb
also remember that -x times -1=x
b.add 25 to both sides
-a=20
multiply -1
a=-20
c.
-t/8=-4
multiply both sides by 8
-t=-32
mutiply -1
t=32
d. -n/-5=-30
mulitply both sides by -5
-n=150
multiply both sides by -1
n=-150
e. multiply both sides by 12
-l=144
multiply b y-1
l=-144
Substitute the x and y values from (3,2).
Formula: y=mx+b
2= 3(3)+b
2-9= -7
y=3x-7

Answer:
I understand why you are asking about this Ammaria, these type of questions take a lot of understanding of graphing. Please feel ok asking me questions :)
Step-by-step explanation:
we are given two points
P1 = (3,3) in the form (x1,y1)
P2 = (7,11) in the form (x2,y2)
slope = m
m = (y2-y1) / (x2-x1)
m = (11-3) / (7-3)
m = 8 / 4
m = 2
now use the slope along with one of the given points, either one will work, i'll use P1 , and put that into the point-slope formula.
y-3 = 2(x-3)
y -3 = 2x -6
y = 2x -3
So with the above formula we can check to see if the points work by plugging them into the formula.
P3 = (5,8)
8 = 2(5) - 3
no point 3 does not work so it's not on the line
P4 = (13, 24)
24 = 2(13) - 3
no point 4 does not work either.
