How many factors are there in the prime factorization of 400?

400 : 2 = 200

200 : 2 = 100

100 : 2 = 50

50 : 2 = 25

25 : 5 = 5

5 : 5 = 1

400 = 2 · 2 · 2 · 2 · 5 · 5

6 prime factors. 2 different prime factors.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
