Answer:

the slope is 3/4

the y-intercept is 4

Explanation:

You want the slope and y-intercept of the line defined by the equation 3x -4y = -16.

Slope-intercept form

The values of interest can be found easily from the slope-intercept form of the equation of the line. Solving for y puts the equation in that form.

3x -4y = -16 . . . . . . given

-4y = -3x -16 . . . . . subtract 3x

y = 3/4x +4 . . . . . . divide by -4

Compare this to the slope-intercept form equation:

y = mx + b . . . . . . . line with slope m and y-intercept b

We see that ...

m = 3/4, b = 4

The slope is 3/4

The y-intercept is 4
