Is it true that if you took an if-then statement inserted a not in each clause and reversed the clauses the new statement would also be true?
If the conditional (if, then) is true, then the contrapositive (reversed; if not, then not) will be also true. And vice versa, if the conditional is false, its contrapositive will be also false. for example,If a graph passes the vertical line test, then it is a graph of a function. (True)If a graph is not a graph of a function, then it will not pass the vertical line test. (True)Yes, but only if the original if-then was true.
Which statement holds true for absolute value functions The absolute value determines the direction in which the graph opens. The coefficient determines the line along which the graph is symmetrical.?
Neither statement is true. The graph of the absolute value of a function which is always non-negative will be the same as that of the original function and this need not open in any direction. Also, the graph of y = abs[x*(x-1)*(x+2)] is not symmetrical so there is no coefficient which will determine a line of symmetry.
is this statement true or falseIf two lines are perpendicular to the same line, then they are parallel to each other.?
true
What must be true about the slope of a line whose graph extends into quadrants II and IV?
it is a negative slope.
What two criteria must be true for a graph to be a proportional relationship?
It must be a straight line. It must pass through the origin.

Is this statement true or false A system of linear equations is a set of two or more equations with the same variables and the graph of each equation is a line?
The statement "A system of linear equations is a set of two or more equations with the same variables and the graph of each equation is a line" is true.

If the line on a graph is solid the line is part of the solution.?
true
What is converse statement?
Statement: All birds lay eggs. Converse: All animals that lay eggs are birds. Statement is true but the converse statement is not true. Statement: If line A is perpendicular to line B and also to line C, then line B is parallel to line C. Converse: If line A is perpendicular to line B and line B is parallel to line C, then line A is also perpendicular to line C. Statement is true and also converse of statement is true. Statement: If a solid bar A attracts a non-magnet B, then A must be a magnet. Converse: If a magnet A attracts a solid bar B, then B must be non-magnet. Statement is true but converse is not true (oppposite poles of magnets attract).
Is it true about a line graph that the slope is constant?
No - a line graph may peak and trough depending on the data marked on the graph - a bit 'like join the dots'.
What is true about the graph of the line y -3x 4?
The line has a slope of -4
is this statement true or falseSlope describes the steepness of a line.?
true
A line graph is commonly used for continuous data?
true
What is the collection of all x y points that make the equation a true statement?
graph
What is the answer to 2x-2y equals -16?
There's no question there yet. That statement is the equation of a straight-line graph, and the coordinates of every point on the graph make the statement true. If you want a single definite number for 'x' and 'y', you need another equation. You always need as many equations as the number of "unknowns" to be found.
