1.) That just means that X will equal 8, so the same as:
3(8)-1
24-1
23
2.) The relationship is a function, there are no repeated elements in the domain(x column), and each domain is pair with one element in the range.
The function is y = 2x+1, when you double x and add 1, you get y.
3.) The relation is not a function for reasons I explained in 2.), x is paired with more than 1 element. The domain is 1,3,-5. Range is -2,2,0,4,-4
(-2,2)(2,-2)
slope = (-2 - 2) / (2 - (-2) = -4/4 = -1
as far as point slope form, there can be 2 answers...
y - y1 = m(x - x1)
slope(m) = -1
using points (-2,2)...x1 = -2 and y1 = 2
now we sub
y - 2 = -1(x - (-2) =
y - 2 = -1(x + 2) <== or could be written as y - 2 = - (x + 2)
y - y1 = m(x - x1)
slope(m) = -1
using points (2,-2)...x1 = 2 and y1 = -2
now we sub
y - (-2) = -1(x - 2) =
y + 2 = -1(x - 2) <== or can be written as y + 2 = - (x - 2)
either one of those answers is ur point slope form
