The graph of y ≤ 3x + 1 and y ≥ –x + 2? Check all that apply. 1.The slope of one boundary line is 2.
1 answer:
Answer:
2.Both boundary lines are solid.
3.A solution to the system is (1, 3).
5.The boundary lines intersect.
Step-by-step explanation:
The give inequalities are:
The slopes of the first boundary line is 3 and the second is -1
Therefore the first statement is false.
Both boundary lines are solid because they contain the equality type of inequality.
The second statement is true.
(1,3) is a solution of both inequalities, because it is in the solution region
since it satisfies both inequalities.
The 3rd statement is true.
The second inequality is shaded above the boundary line because the origin does not satisfy this inequality..The two slopes are not the same so the boundary lines will intersect.

Step-by-step explanation:
Hi,
We're dealing with linear functions.
We have here the first function.
That's a linear function, with slope, and no linear coefficient since
But on the other hand, the functions below, they all describe parallel lines, since their slope has the same value. I've changed the letters to make it easier the comprehension.
Even though each one has the same slope value, they have different non zero linear coefficients, {-6,-18,6,18}. Unlike, the first one
A possible solution would be adjusting any of these, whose operation would result in g(x)=3x, but
