Answer 2

To graph the equation y = 3x and find the point where y = -3, we can substitute the value of y into the equation and solve for x.

Given: y = -3

Substituting y = -3 into the equation: -3 = 3x

Now, we can solve for x: Divide both sides of the equation by 3: -3/3 = 3x/3 -1 = x

So, when y = -3, x = -1.

Now, let's plot the graph of y = 3x:

To draw the graph, you can choose a range of x-values and calculate the corresponding y-values based on the equation y = 3x. Let's choose a range of x-values from -5 to 5.

For x = -5: y = 3(-5) = -15

For x = -4: y = 3(-4) = -12

For x = -3: y = 3(-3) = -9

For x = -2: y = 3(-2) = -6

For x = -1: y = 3(-1) = -3

For x = 0: y = 3(0) = 0

For x = 1: y = 3(1) = 3

For x = 2: y = 3(2) = 6

For x = 3: y = 3(3) = 9

For x = 4: y = 3(4) = 12

For x = 5: y = 3(5) = 15

Now, we can plot these points on a graph and connect them to form a line:

The graph of y = 3x is a straight line passing through the origin (0, 0) with a slope of 3. The point where y = -3 corresponds to the x-coordinate -1, so it lies on the line.
