To graph the equation y = -1/2x - 4 using the slope and y-intercept,

Question

you would have to do which of the following?

Answer 1

The given equation y = -1/2x -4

To compare the  general slope - intercept form is y = mx+b

Slope m is -1/2 and y - intercept b is -4

The equation y = -1/2x -4 graph is

Answer 2

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

The equation is y  = (- 1/2)x - 4.

It is already in slope - intercept - form.

So, compare the equation with slope - intercept form y = mx + b.

slope = - 1/2 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 = - 1/2

Start at point (0, - 4), move 1 unit down and 2 units right, then plot the point (2, -5).

Draw a line through these points.
