Hi Tracy;
ANSWER TO YOUR SECOND QUESTION...
2y+5= 6x
We need to isolate y such that x will be multiplied by its coefficient and added to the constant. This is to produce the result of y.
Let's subtract 5 from both sides...
52y+5= 6x5
2y=6x5
Let's divide both sides by 2...
(2y)/2=(6x5)/2
y=3x+(5/2)
We will replace y with f(x)...
f(x)=3x+(5/2)
f(x) means function of x.
ANSWER TO YOUR FIRST QUESTION...
The y value of both points is the same...
y=2
This is a straight horizontal line.
The slope is zero, NOT undefined. It is NOT
undefined because slope, by definition, is the changeofy divided by the changeofx, also known as riseoverrun. The changeofy is zero. Henceforth, the numerator is zero. The slope can
only be characterized as undefined if the denominator, changeofx, is zero.
The equation is...
y=2
