A slope of zero means that the line is flat. In other words, change in "y" is equal to zero. Such an equation, using general representation of linear equation, is written as
y=mx+b but m=0
then, y=b
In the current scenario, b=-8
Therefore, the line equation is
y=-8
The best way too solve it is to cross multiply. When you get the answer tell me and I’ll check it
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above
since we know that's its slope, then
so then we're really looking for the equation of a line whose slope is -2 and passes through (2 , 1)
Hello from MrBillDoesMath!
Answer:
All real x
Discussion:
Take any real number, say, P. Then solve
f(x) = (x-2)2 + 2 = P => (subtract 2 from both sides)
(x-2)2 = P -2 => (divide both sides by 2)
(x-2) = (1/2) (P-2) => (add 2 to both sides)
x = (1/2)(P-2) + 2
Conclusion: for any real number range value, P, there is an x (given by the above formula) such that f(x) = P. In other words, the range of f is all real numbers x
