To find the slope you use the slope formula y2-y1 / x2-x1. So use two point on the line we will make ours (1,2) and (3,4). Substitute to make 4-2 / 3-1 = 1/1 so using the rise over run method. The line rises up one and runs by one. The slash mark means divide, it's easiest in a fraction.
Also if you come across the equation y=mx+b, m is the slope and b is the y-intercept, this is called slope intercept formula.
4z ≥ 7
divide seven by four
z ≥ 1.75
or, if you need it in fraction form, it would be
z ≥ 7/4
The correct answer is C) F(x)= x^2+4
one way to tell this is correct is the y-intercept is at positive 4
Answer:
area is length * width
