$( \frac{a}{b} )( \frac{c}{d} )= \frac{ac}{bd}$ so
$( \frac{3}{10} )( \frac{-4}{5} )= \frac{3*-4}{10*5}= \frac{-12}{50}= \frac{-6}{25}$

3[x]+9 what is the graph?

ipn [44]

So, you can do this one of two ways.

The first is knowing what the numbers in your equation represent:

For example: y=mx+b in this case "b" is 9. b is the y-value when x=0. So the first point on our graph is (0,9). Next we have to pick an xvalue to solve for another y-coordinate.

I chose x= -3. Plug x into the equation to get y.
y=3x+9
y=3(-3)+9
y=(-9)+9
y=0

So, our second point is (-3,0).

connect the points with a ruler to graph the line.
