Find a linear inequality with the following solution set. Each grid line represents one unit.
Give your answer in the form ax + by + c > 0 or ax + by + c >= 0 where a, b and c are integers with no common factor greater than 1.)
Find two integer points on the line like -5, -3 and 0,1 to compute the slope = m = 2
y = 2x + b b is the y axis intercept = 1
so the line equation is y = 2x + 1
The shaded aea is everything ABOVE the line....but does not include the dashed line:
y > 2x+1 now re-arrange into the requaested form
-2x + y -1 > 0 Done !
