Step-by-step explanation:
Answer: y = 
+ 30/11
Step-by-step explanation:
Two line are said to be perpendicular to each other if the slope of the first line = -1 / the slope of the second line , that is
If the slope of the first line is M1 and the slope of the second line is M2 , then M1 = -1 / M2.
From the equation given , M1 = - 11 , that means M2 = 1 / 11
Using the formula y - y1 = m ( x - x1) to calculate the equation , we have
y - 3 = 1/11 ( x - 3)
Multiply through by 11 , we have
11 ( y - 3 ) = x - 3
11y - 33 = x - 3
11y = x + 30
y = x/11 + 30/11
Answer:
1st and 2nd statements are true.
Step-by-step explanation:
We are asked to choose the correct statements that can prove that quadrilateral DEFG is a parallelogram.
We will use parallelogram properties to answer this problem.
Since we know that a parallelogram has two sets of opposite angles congruent, therefore, 1st option is a correct choice.
Since a parallelogram has one set of opposite sides that are both congruent and parallel, therefore, second statement is true.
Since the consecutive angles of a parallelogram are supplementary, therefore, 3rd statement is not true.
Since the diagonals of parallelogram bisect each other, therefore, 4th statement is not true.
