Y=mx+b is the formula you need to get it in
start with the equation 8x-2y=5
so we want to get y by itself and everything else on the right side of the equation. to do this first subtract -8x from the left side and put it on the right side. this step would look like this:
8x-2y=5
-8x-2y=5 -> -2y=5-8x
-------------
next take and divide -2 from both sides of the equation. this would look like this:
-2y= 5 -8x
÷-2y=÷-2÷-2 -> y= -5/2 +4x
-------------------
so your new equation is y=4x-5/2 y=mx+b tells you the slope and y-intercept. m=slope and b=y-intercept. so in this case 4 is your slope and -5/2 is your y-int
Answer:
False if i'm wrong so sorry!!
Step-by-step explanation:
For this case we have the following vectors:
u = (9, 0)
v = (0, -9)
Using product point we have:
u.v = (9, 0). (0, -9)
u.v = (9) * (0) + (0) * (- 9)
u.v = 0 + 0
u.v = 0
If the scalar product of two vectors is zero, both vectors are orthogonal.
Answer:
C. orthogonal
