Y + 3x = -4 need to graph it..

Question

Need to find answer and graph it..Teacher did it in class and made it look soo easy!

Answer 1

Given that y + 3x = -4.

y = -3x - 4

The general form of slope intercept form of line is y = mx + c.

Here slope m = -3 and y-intercept = -4

Graph-;

1)Draw the graph of y = -3 - 4.

2)It represents a straight line.

Answer 2

The equation y + 3x = - 4

Write the equation in slope-intercept form y = mx + b, where m is slope and b is y-intercept.

Now the equation is y = - 3x - 4

slope = - 3 and y-intercept is - 4.

y-intercept is - 4, so the line crosses the y-axis at (0, - 4)

Using slope find the next point.

Slope = rise/run = 3/-1

Start at point (0, - 4), move 3 units up and 1 unit left, then plot the point (-1, -1).

Draw a line through these points.
