75) The domain is all values of x and range is all values of y. Given this, domain is -1 <u><</u> x <u><</u> 6. Range is 1 <u><</u> y <u><</u> 5. It is not a function because it does not pass the vertical line test. (Shown in image. Blue line is the vertical line and green line is the line shown based on the graph.)
76) The ordered pairs are:
Answer:
ONE SOLUTION
Step-by-step explanation:
When two points on a line are given, the equation of the line is given by the formula:
where and
are the points on the line.
Here, the first set of points are: and
.
Therefore, and
.
The line passing through this is given by:
∴ 2x + y - 1 =0
Now, for the second line, the points are:
and
.
Therefore,
∴ 2x - y + 2 = 0
Now, to determine the number of solutions the two equations have, we solve these two equations,
Adding Eqn(1) and Eqn(2) we get:
4x = -1
And .
Since, we arrive at unique values of 'x' and 'y', we say the lines have only one unique solution.
