Answer:
U have to say the numbers for me to figure out the problem
Step-by-step explanation:
We can use the points given to solve for the slope.
Slope formula: y2-y1/x2-x1
7-7/-1-5
0/-6
Since the numerator is 0, the slope is 0.
Best of Luck!
Answer:

Step-by-step explanation:
we are given that

we want to figure out x
remember that,
In <u>unit</u><u> </u><u>circle</u> x coordinate is considered cos and y coordinate is considered sin
so in order to figure out x we should figure out the value of <u>cos</u> to do we can consider <u>Pythagoras</u><u> trig</u><u> </u><u>indentity</u>
given by

we are given sin=-√7/4 thus
substitute:

simplify square:

move left hand side expression to right hand side and change its sign:

simplify Substraction:

square root both sides:

since in unit circle cos is x and P belongs to Q:IV negative cos isn't applicable
hence,

Answer:
