Plotting coordinates can be a little confusing, but it doesn't have to be as long as you remember a few important details. The first number in the coordinate set tells you how far right (for a positive number) or left (for a negative number) you need to travel on the x-axis. The second number in the coordinate set tells you how far up (for a positive number) or down (for a negative number) you need to travel on the y-axis. Any set of coordinates can be represented by the variables x and y. If you picture (x, y), it will help you remember the x-coordinate comes first, so you will travel either right or left before travelling up or down.
Answer:
x = ± 5
Step-by-step explanation:
x² - 25 = 0 ( add 25 to both sides )
x² = 25 ( take square root of both sides )
x = ± 
= ± 5
That is x = - 5, x = 5
Answer:
x > -3 and y ≥ 1/2x - 2
Step-by-step explanation:
blue line = x > -3
red line = pass (0, -2) (4, 0)
y = 1/2x - 2

Answer:
The value of k with given points and slop = 11
Step-by-step explanation:
Given that a line passes through two points having slop (m) = 2
co ordinates of points are (1 , 3) and (5 , k)
Now slop of line can be written as,
Slop = 
Or, m =
2 = 
Or, 2 = 
So , k - 3 = 8
∴ K = 8+3 = 11
Hence the value of k with given points and slop = 11 Answer
