Given:

Points ( 0, -3)

Slope: 4/3

x1 = 0

y1 = -3

m = 4/3

Determine the equation of the line in slope-intercept form.

Slope-intercept form:

y = mx + b

Solution:

Before we can proceed to slope intercept form, we must designate the values in point-slope form denoted as,

y - y1 = m(x - x1)

y - (-3) = 4/3(x - 0)

y + 3 = 4/3x

Transpose 3 on the other side of the equation, note that when transposing a number, the sign changes.

y = 4/3x -3

Final answer:

y = 4/3x -3
