On the grid draw the graph of y = 3x + 2 for values of x + 2 for values of x from -2 to 2
sladkih [1.3K]

Answer:

The required graph is shown below.

Step-by-step explanation:

Consider the provided equation y=3x+2

We need to draw the graph of the equation.

Put x=0 in the above equation.

y=3(0)+2

y=2

The coordinate is (0,2).

Put y=0 in the given equation.

0=3x+2

-2=3x

x=\frac{-2}{3}

The coordinate is (\frac{-2}{3},0).

Now draw the graph by using the above coordinates.

The required graph is shown below.

CAN YOU HELP ME!
Nat2105 [25]

Answer:

B) 15/(9+(-9))

Step-by-step explanation:

Be careful of the parentheses because if you just write out 15/9+(-9),

it's technically, saying that 15/9+(-9)=5/3+(-9)=5/3-9, and that's different from what you want to express, mathematically.
