9) Which equation represents the line that passes through the point (3,4) and is parallel to the x-axis?

kobusy [5.1K]

Since the line is parallell to the x-axis we know the slope is zero: $m=0$

Using the point-slope formula we can substitute know values:
$y=mx+b$
$4=0(3)+b$
$b=4$
$y=0x+4$
$y=4$

You could also jsut do it by inspection: since it passes through (3,4) and is horizontal it must cross at (0,4) i.e. all y=4.

Which expression is equal to 4/8

givi [52]

<h2>Fractions</h2>

Which expression is equal to $\large\tt \frac{4}{8}$ ?

Option 1

$\large \tt 4 \times \frac{1}{2} = \frac{4}{1} \times \frac{1}{2} = \red{\frac{4}{2}}$

Option 1 is not equal to $\large\tt \frac{4}{8}$

$\huge{\overline{\qquad\qquad\qquad\qquad \: \: \: }}$

Option 2

$\large \tt 3 \times \frac{1}{5} = \frac{3}{1} \times \frac{1}{5} = \red{\frac{3}{5}}$

Option 2 is not equal to $\large\tt \frac{4}{8}$

$\huge{\overline{\qquad\qquad\qquad\qquad \: \: \: }}$

Option 3

$\large \tt 3 \times \frac{1}{8} = \frac{3}{1} \times \frac{1}{8} = \red{\frac{3}{8}}$

Option 3 is not equal to $\large\tt \frac{4}{8}$

$\huge{\overline{\qquad\qquad\qquad\qquad \: \: \: }}$

Option 4

$\large \tt 4 \times \frac{1}{8} = \frac{4}{1} \times \frac{1}{8} = \green{\frac{4}{8}}$

Therefore, option 4 is equal to $\large\tt \frac{4}{8}$
