Since the slope stays the same as it's parallel, we have y=(3/4)x+b. Plugging (2,-1) in, we get -1=3*2/4+b=6/4+b=1.5+b. Subtracting 1.5 from both sides, we get -2.5=b and our equation being y=(3/4)x-2.5 (since in y=mx+b, y and x remain as variables)
The relation is <em>not a function</em> if any x-value is repeated.
Assuming you have
(x, y) = (3, 10), (__, 20)
if x = 3, the relation is not a function.
Answer:
-3
Step-by-step explanation:
The slope of a line can be calculated with the formula (y2-y1)/(x2-x1)
In this case we have:
(-4-(2))/(7-5)
(-6)/(2)
-3
