Question 858043: teI need to create my own equation written in standard form and:
(A) Determine any point that is a solution and will be on this line. Justify your answer algebraically.
(B) Explain how to find the x- and y- intercept(s) using complete sentences. Write the intercepts as ordered pairs.
(C) Rewrite the equation using function notation. Grapht he function and show the intercepts.
I am lost. please help.
Answer by rothauserc(4718)   (Show Source):
You can put this solution on YOUR website! standard form for a line is y = mx +b where m is the slope and b is the y axis intercept,
for example, y = 2x +1
a) say x = 1, then y = 3 (substitute for x in our example) and the point is (1, 3)
b) To find the y axis intercept let x = 0 and the intercept is (0, 1)
now solve our example for x, x = (y - 1) / 2, now let y = 0 and substitute in our equation for x to get the x axis intercept, (-1/2, 0)
c) rewrite our example in function notation, f(x) = 2x + 1
