For each point, put the first number into the equation in place of 'x',
and put the second number into the equation in place of 'y', and then
see whether the equation makes sense. If it does, then that point is
on the line. If it doesn't, then it's not.
Example:
The equation is <u>y = 6x - 4</u>
Choice 'C', point (-4, 0)
Put the ' -4 ' in place of 'x', and put the ' 0 ' in place of 'y'.
Then the equation says
0 = 6(-4) - 4
0 = -24 - 4
<em> 0 = -28</em>
Does that make sense to you ? If it does, then math is not your game.
The equation is not a true statement.
So the point (-4, 0) in not on the line.
x + y = 5..........(I)
or,x=5-y
-2x + y = 2..........(II)
replacing x=5-y in equation (II),.we get ...
-2(5-y)+y=2
-10+2y+y=2
or,3y=12
y=4
now.,,
putting y=4 in equation (I)
x+4=5
x=5-4
x=1
hence x=1
You're looking for the percentage in decimal form in the equation. We'll call it x for right now. So whatever x is it will be multiplied to 3.20 and subtracted from 3.20 to equal 2.40. So, our equation will look like this
3.20-x(3.20)=2.40
subtract both sides of the equation by 3.20 to get
-x (3.20)=2.40-3.20
-x (3.20)=-.80
now divide both sides of the equation by -3.20 to single out x on the left side
x= -.80/-3.20
x=.25
to turn this back into a percentage, we move the decimal to the right 2 places
.25=25%
Answer:
1/7 = 1/7
Step-by-step explanation:
The equation is written in the slope-intercept form:
Where:
m = Slope
b = y-intercept
From the equation we can conclude that the y-intercept is:
We can find the x-intercept as follows:
The x-intercept is:
(3,0)
The graph is:
