Answer:
It doubled up is what you could say
The order of division determines the numerator and the denominator and this can effect the value. And example of this:
3/2 = 1.5
2/3 = 0.6667
Whereas, multiplication is not affected by the order:
2 x 3 = 6
3 x 2 = 6
Let's make it an expression.
Three half's= 3/2 Plus= + one fifth= 1/5
We need to turn 3/2 and 1/5 so that they have the same denominator. Let's use 10.
3/2→15/10 1/5→2/10
15/10+2/10=17/10=1 7/10
So, three half's plus one fifth is 1 7/10.
Slope = (-7+4) / (7-1) = -3/6 = -1/2
using point (1,-4)
equation y + 4 = -1/2(x - 1)
answer is C.
y + 4 = -1/2(x - 1)
