Answer:
B. y ≤ 1/2x + 3
Step-by-step explanation:
To write the equation of the inequality, use the linear equation form y = mx + b. The y-intercept is b and is where the line intersects the y-axis. Here b = 3. You can find the slope m by counting between points the vertical and horizontal distances. Here it is 1/2. Substitute m = 1/2 and b = 3.
y = 1/2x + 3
Since this is an inequality and a solid line has been used, you must use ≤ and ≥. To determine which is for this equation, test the point (0,0) in each.
y ≤ 1/2x + 3 y ≥ 1/2x + 3
0 ≤ 1/2(0) + 3 0 ≥ 1/2(0) + 3
0 ≤ 3 True 0 ≥ 3 False
Since (0,0) is a part of the set of solutions, the equation which is true is the correct equation.

Answer:
option D. Neither
Step-by-step explanation:
y-4=7(x-6)
using (5,4):
4-4=7(5-6)
0=7(-1)
0=-7
using (6,5):
5-4=7(6-6)
1=7(0)
1=0
so option D is the answer
