Step 1
<u>Find the equation of the line AB</u>
we know that
the equation of the line into point-slope form is equal to
Let
<u>Find the slope m</u>
we know that
the slope between two points is equal to
substitute
with the slope m and point A find the equation of the line AB
or
with the slope m and point B find the equation of the line AB
we will proceed to verify each case to determine the solution of the problem
Step 2
<u>Verify case A</u>
<u>Case A)</u>
the slope of the line is
but the point -----> not lie on the line AB (see the graph)
therefore
the case A is not the solution
Step 3
<u>Verify case B</u>
<u>Case B)</u>
the slope of the line is
and the point -----> is the point A
therefore
the case B is a solution
Step 4
<u>Verify case C</u>
<u>Case C)</u>
the slope of the line is
but the point -----> not lie on the line AB (see the graph)
therefore
the case C is not the solution
Step 5
<u>Verify case D</u>
<u>Case D)</u>
the slope of the line is -----> the slope is not equal to the slope AB
and the point -----> not lie on the line AB (see the graph)
therefore
the case D is not the solution
<u>the answer is</u>
The equation is a point-slope form of the line AB
The answer is 35.1 cm².

Answer:
step by step:
3x+5=-2
move constant to the right-hand side and change it's sign
3x=-2-5
Calculate the difference
3x=-7
Divided both sides of the equation by 3
