Which of the following could be true if y ≤ -75?
ch4aika [34]

Hello!

Lets go through each choice, and determine if it is correct.

So, the symbol ≤, means less than or equal to. So our answer must be less than -75 or -75 on the dot.

A: y = 75

Okay, so we can tell this one is wrong off the bat. 75 is much more than -75. (Make sure you notice the symbol!) So it cannot be equal to said answer. A is wrong.

B: y =-74

Another trick question! When you are in the negatives, less is more! So -74 is actually greater than -75. This is also incorrect!

C: y > -75

This one is straight forward. Our equation up top strictly says <em>less than or equal too</em>, while C says greater than. Incorrect!

D: y = -75

The last answer! We see that the symbol in our equation up top says less than or equal too, and y = -75 is equal. This is the correct answer.

Our correct answer is D: y = -75

Write the equation of the line passing through the points (-7,9) and (7,5).
inn [45]

Answer:

y=-\frac{2}{7} x+7

Step-by-step explanation:

First Solve For The Slope Using The Two Given Points!

M = Slope

M = \frac{y2-y1}{x2-x1}

M = \frac{5-9}{7--7}           Two negative signs together makes addition!

M = \frac{-4}{14}               Move the negative sign (only if the fraction has a negative)

M = -\frac{4}{14}            Simplify

M = -\frac{2}{7}              Final Answer

Then see how many units the graph goes up = y-intercept

Answer: 7
