Linear line is a straight line. In this equation which is in slope intercept form (y=Mx+b) M the number in front of the x is the slope (also known as common different) -3 is the slope, you do rise rise over run -3(down 3 to the right 1) or (up 3 to the left 1) and 3 is the y intercept. Y intercept is when x=0 (3,0). If you graph the point (3,0) you go down 3 to the right 1.

Emily needs enough Fabric for 3 1/2 hats. Since she has half a hat done. If each bag requires 1 2/7 ft of Fabric, how much fabri
kow [346]

first off let's convert the mixed fractions to improper fractions.

\stackrel{mixed}{3\frac{1}{2}}\implies \cfrac{3\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{7}{2}} ~\hfill \stackrel{mixed}{1\frac{2}{7}}\implies \cfrac{1\cdot 7+2}{7}\implies \stackrel{improper}{\cfrac{9}{7}}

she already did half a hat, so we can say   \cfrac{7}{2}-\cfrac{1}{2}\implies \cfrac{7-1}{2}\implies 3

so she only needs enough fabric to make 3 more full hats, we know each one uses 9/7 ft, so

3\cdot \cfrac{9}{7}\implies \cfrac{27}{7}\implies 3\frac{6}{7}

The average human reaction time from eye to finger is 0.16 second. How is this expressed as a fraction?
xxTIMURxx [149]

the second (0.16) is in two decimal places, so divide 16 by 100

\frac{16}{100}

to express in the simplest form, divide the numerator  and the denominator by 4
