Well according to the slope intercept equation.
Y = mx +/- b
The slope is the value m
The y intercept is b
To graph the function, one sure way to do it is simply make a table of values picking any x values that fall within the graph space, and finding out the resulting y values and using the points to graph.
For instance for the first graph, if x = 0, y = 5, that is one possible point. Keep on choosing x values to graph.

Answer:8+x-7+8x+17
9x=18
X=2
Step-by-step explanation:
Place the x (1.5) and y (5) values into the equation, and solve. If the statement you get is true, it is a solution.
2x - y = -1
2(1.5) - 5 = -1
3 - 5 = -1
-2 ≠ -1
Since this is a false statement, negative 2 is not equal to -1, the ordered pair is NOT a solution. I hope this helps and have a great day!
