They are parallel when the slopes are the same
example:
y=2x+3
y=2x-5
B. Its suggesting something bigger than -5
The mapping rule for 90 degrees counterclockwise would be (-y,x). So if you had (x,y) it would transfer to (-y,x). Yours is wrong it should be (4,-3). Remember
-(-4) is 4 and -3 stays as -3.
Basically, memorize these mapping rules.
Hope this helped!
Because they are math buddies say 2x2=4. You can divide 4÷2 and get your original factor (2)... Sorry if it's wrong I think that's what it means ,hope it helps!
A)
x 0 1 2 3 4
y 5 10 15. 20. 25
b) x 0 1 2 3. 4
y 1. 10. 37. 82. 145
