Answer 2

Graph of the Equation 3x - y + 2 = 0

To graph the equation 3x - y + 2 = 0, we need to rearrange it in the form y = mx + b, where m is the slope and b is the y-intercept.

Let's rearrange the equation:

3x - y + 2 = 0

Subtract 3x from both sides:

-y = -3x - 2

Multiply both sides by -1 to isolate y:

y = 3x + 2

Now we have the equation in slope-intercept form, where the slope (m) is 3 and the y-intercept (b) is 2.

To graph this equation, we can plot a few points and draw a line through them. Let's choose some x-values and calculate the corresponding y-values:

When x = 0: y = 3(0) + 2 = 2 So we have the point (0, 2).

When x = 1: y = 3(1) + 2 = 5 So we have the point (1, 5).

When x = -1: y = 3(-1) + 2 = -1 So we have the point (-1, -1).

Now we can plot these points on a graph and draw a line through them.


The graph of the equation 3x - y + 2 = 0 is a straight line with a slope of 3 and a y-intercept of 2.
