Graph the linear equation 5x-4y < 20

Using a graphing calculator:

(See attached image file)

Step-by-step explanation:

Start by plotting given key featuresBased on the problem, we know that the x-intercept is (0,4) We find this by plugging in 0 for y, and solving for x  (5x = 20)(x = 20/5 = 4)        (4, 0)   We can also easily solve for the y-intercept, which is (0,-5)We find this by plugging in 0 for x, and solving for y(-4y = 20)(y = -5)      (0, -5)   Since we know that the equation is linear, seeing as the highest exponent is 1, we know that these two points have to be connected by a single, straight line.Finally, we shade in the side to the LEFT of the line. This is because the equation asks for LESS THAN. If however the question had been 5x-4y>20, we would shade in the region to the right.
