This answer involves rearranging the equation to make y the subject.

The slope m=4/3 and the y-intercept b=7/3.

Explanation:

Slope-intercept form of a line is:

y=mx+b where m is the slope and b is the y-intercept

In this case it is simply the algebra of rearranging 4x-3y-7=0 to make y the subject:

4x-3y-7=0 (add 7 to both sides)
4x-3y=7 (subtract 4x from both sides)
-3y=7-4x (divide both sides by -3)
y=-(7-4x)/3 =4/3x-7/3

From the rearranged equation the slope m=4/3 and the y-intercept b=7/3.
