<u>Part 1)</u> Which ordered pair is a solution to this equation?
Substitute the values of each pair ordered in the equation to find the solution
A.
<u>The pair ordered A is a solution</u>
B.
<u>The pair ordered B is not a solution</u>
C.
<u>The pair ordered C is not a solution</u>
D.
<u>The pair ordered D is not a solution</u>
therefore
<u>the answer part 1) is</u>
The ordered pair A. is a solution of the equation
<u>Part 2) </u>The equation of a line is
we know that
the x-intercept is when the value of y is equal to zero
so
for
<u>Find the value of x</u>
substitute
therefore
<u>the answer part 2) is </u>
The x-intercept is equal to
<u>Part 3) </u>What is the slope of the line passing through the points and ?
we know that
the slope of the line is equal to
Substitute the values in the formula
therefore
<u>the answer part 3) is</u>
The slope of the line is equal to
<u>Part 4)</u> Select all statements that are true about the linear equation.
<u>Statements</u>
a) The graph of the equation is the set of all points that are solutions to the equation
<u>This statements is True</u>------> Any point that belongs to the graph of the equation is the solution to the equation
b) The point is on the graph of the equation
substitute the values in the equation
----> the point is on the graph of the equation
therefore
<u>This statements is True</u>
c) The point (1, 1) is on the graph of the equation
substitute the values in the equation
----> the point is on the graph of the equation
therefore
<u>This statements is True</u>
d) The graph of the equation is a single point representing one solution to the equation
<u>This statements is False</u> ------> the equation graph are infinite points, representing infinite equation solutions
