Answer:
Step-by-step explanation:
Slope of a line passing through two points 
and 
is given by the formula,
Slope = 
Slope of the line PQ passing through the two points P(-8, 2) and Q(4, 2) will be,
Slope '
' = 
= 0
Therefore, slope of the line PQ parallel to the x-axis = 0
Slope of the line MN passing through the points M(8, 6) and N(8, -8) is,
Slope '
' = 
= ∞
Therefore, slope of the line MN parallel to y-axis is undefined.
Since, angle between the x-axis and y-axis is 90°,angle at the intersection point between the lines parallel to x and y axis will be 90°.
These lines are perpendicular to each other.
To find area u have to multiply the sides so it should be 7x7 or 13x7 it shouldnt be 13x7x7
250 cm because area equals LxW and 25x10=250
All we have to do is multiply them by each other accept we change the percent into a decimal.
65% = 0.65
soooo
0.65 x 65 = 42.25
<span>answer? =42.25
</span>i hope this was helps:)
and don't forget 2

Answer: 
Step-by-step explanation:
Find the x-coordinate of the vertex with this formula:
In this case:
Substituting values, we get:
Now we can substitute the coordinates of the vertex into the equation 
and then solve for "c".
Then:
