Answer:
m = 3/4; b = -3
Step-by-step explanation:
1) First, put the given equation into slope-intercept form. This is so we can identify its slope and y-intercept easily. Isolate y:
2) Lines that are in slope-intercept form are represented by the formula . The number in place of
, or the coefficient of the x-term, represents the slope. The number in place of
represents the y-intercept. So, the slope of
is
, and its y-intercept is -3.
Now, recalling that for 1 yard, there are 3 feet, therefore 
and keeping in mind that, there are 4840 yd² in 1 acre, then
