Evan has graphed the point (5, 7) and he wants to reflect it over the line y=-2/5x+6. he predicts that the reflected point will have coordinates (2, 2). without graphing, can you confirm his answer or show that he cannot be correct?

Given that Evan has graphed the point (5, 7) and he wants to reflect it over the line y=-2/5x+6. He predicts that the reflected point will have coordinates (2, 2).

Now we have to check if his answer is correct or not without graphing. Yes this is possible without graphing.

If his answer is correct then the line passing through points (5,7) and (2,2) will be perpendicular to the given line.

slope of line passing through the points (5,7) and (2,2) is given by :

slope of the given line is

We know that If the two lines are perpendicular then product of their slopes equals -1

Which is not -1. That means both lines are not perpendicular.

Hence his answer is wrong.

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
