Answer:
Blue - y=-2
Red-
Parallel to Red-
Perpendicular to Red-
Step-by-step explanation:
The slope intercept of a line is y=mx +b where
- m is the slope which is calculated as the vertical distance divided by the horizontal distance between two points.
- b is the y-intercept for value on the y-axis for which the line crosses it.
The Blue line intercepts the y-axis at -2 so b=-2. It has no vertical change since it is a horizontal line. This means the slope, m, is 0. m=0. It's equation is y=0x-2
y=0-2 since anything times 0 is 0.
y=-2.
The red line intercepts the y-axis at 2 so b=2. It intercepts the x-axis at (-3,0). Between these two intercepts we can find the slope:
Slope:
We substitute and
The red line has equation .
Parallel lines have the same slope with a different y-intercept. So we write a line where m=2/3 and b is something else.
Perpendicular lines have a negative reciprocal slope to the original. So we write the line where m/-3/2.
Answer: (x,y) = (-10, -9)
Step-by-step explanation:
(By replacement method ...)
1- x = -2-8 it's the same thing as x = -10.
2- Replace the given value of x in equation 3x - 4y = 6
Replacing ...
3 * (-10) -4y = 6
3- Then, Multiply 3 by -10;
4) Move -30 to the right side of the equal sign, getting: 6 + 30.
-4y = 36
5) Multiply by -1
-4y * (- 1) = 36 * (- 1) is equal to 4y = -36
6) The four is multiplying the y, so pass the four <u>dividing</u>, getting:
-36/4
The ratio of -36 by 4 equals <u>-9.</u>
Therefore...
x = -10
y = -9
Do you want to get the variable by itself.
In order to do that subtract x on both sides.
-2x+9=-5
Then subtract 9 on both sides
-2x=-14
Divide by -2 on both sides
X=7
Step-by-step explanation:
2x+3=8
2x=8-3
2x=5
2x/2=5/2
x=5/2
