Lines that are perpendicular to another line has an opposite reciprocal slope. (opposite meaning to negate the number).
Lines that are parallel have the same slope.
But the line you provided is a vertical line, and vertical lines are undefined. There is no possible perpendicular or parallel line. Maybe you gave the wrong equation and didn't put it in <em>y=mx+b</em> form. If so, you can correct it in the comments, and if not, that's you answer!

Hello! Slope is rise/run. The formula for finding slope is y2 - y1 / x2 - x1, where you subtract the first x and y-coordinates from the second x and y-coordinates. We have the points (-2, -3) (first) and (4, 0) (second). Let's find what the numbers represent and then solve.
y2: 0
y1: -3
x2: 4
x1: -2
It becomes set up as 0 - (-3) / 4 - (-2). 0 - (-3) is 3. 4 - (-2) is 6. Keep in minid that when you subtract a negative number, you are actually adding. 3/6 is 1/2 in simplest form. There. The slope is 1/2.
Answer:
The price of the tv before tax is 410
Step-by-step explanation:
Let x = price of tv before tax
tax = x* 9%
tax = .09x
The total cost is price of tv before tax plus tax
total cost = x + .09x
total cost = 1.09x
446.90 = 1.09x
Divide each side by 1.09
446.90/1.09 = 1.09x/1.09
410 = x
The price of the tv before tax is 410
Answer:
y=-2x-2
Step-by-step explanation:
Subtract 4, eliminate parentheses, and collect terms.
y = -2x +2 -4
y = -2x -2
