When you see the word "parallel", you know the new line will have the same slope.
parallel to y=4x-3
So, the new line will have a slope of 4
"Indicate the region where y≥ 4x-3
Plot y= 4x-3 by finding the points that make it true. For example, (y = 0, x = 3/4), (y = 1, x = 1) and so on. Draw the line on your graph paper, then shade in the portion above the line, because you want y to be greater then.
y = 4x + b
b is the y intercept ( point y when x = 0)
Insert new coefficients:
-1 = 4(0) + b
b = -1
y = 4x - 1
