Answer:
Step-by-step explanation:
The y-intercept cannot be (2,-8). The x-coordinate of the y-intercept is 0.
Point-slope equation for line of slope -5 that passes through (2,-8):
y+8 = -5(x-2)

Answer:
The domain: All real numbers.
The range: y>0
Step-by-step explanation:
Domain means all possible x values, and by looking at the graph it covers all real numbers.
Range means all possible y values, and since the x axis is a horizontal asyntope, the graph will never touch the x axis, which is why the range is y>0.
