0.27 ÷ 0.03 = explain each and every step in this process
GREYUIT [131]
0.27 divided by 0.03 = 9


think of it this way it's like doing it 27 divided by 3 which is = 9


but then u see
9x3=27
9x0.3=2.7

so that must mean
9x0.03=0.27
u basically move the decimal point, in this problem its moved 2 or 3 times.

Find the equation of the line that contains the points (4,2) and (6,10). Write the equation in the form y=mx+b and identify m an
Fantom [35]
Points (4,2) and (6, 10)

Eqn:
y - y = m(x - x)
y - 2 = [(2-10)/(4-6)] (x - 4)
y - 2 = (-8/-2) (x - 4)
y - 2 = 4(x-4)
y - 2 = 4x - 16
y - 2 + 2 = 4x - 16 + 2
y = 4x - 14

Therefore the slope (m) would be 4 and the y intercept (b) would be -14.
