The first choice is your answer. Since it’s substitution, you have to plug in x to the x in the bottom equation
A) A straight line.
This is so because the equation is of the first degree (the largest power of x is one). Thus making it a linear equation. The gradient in the equation here (3/4) shows that when you increase the value of x by 1, they value for y increases by 3/4. Since the increments are constant, you will see that the function is a straight line if you draw it.
You are given a parallelogram <span>ABCD</span> with the following Cartesian plane coordinates:<span>A:(−7,3)</span><span>B:(−5,7)</span><span>C:(1,7)</span><span>D:(−1,3)</span>and are asked to provide a parallelogram <span><span>A′</span><span>B′</span><span>C′</span><span>D′</span></span> that is congruent to it. The easiest way to do this is to perform a simple shift (either upward or downward) of your original figure. Let us perform a downward shift of 1 unit on it for simplicity:<span><span>A′</span>:(−7,2)</span><span><span>B′</span>:(−5,6)</span><span><span>C′</span>:(1,6)</span><span><span>D′</span>:(−1,2)</span>Parallelogram <span><span>A′</span><span>B′</span><span>C′</span><span>D′</span></span> is congruent to parallelogram <span>ABCD</span><span> because their corresponding sides and angles are equal.</span>
8-3=$5
10-4=$6
That's how much each person has.
