it might be the second one not sure
Answer:
y = -1/2x + 13/2
Step-by-step explanation:
The slope of a line that is perpendicular to a line will be a negative reciprocal. When you rewrite 2x-7=8 into slope-intercept form, you get y=2x-8. The negative reciprocal of the slope 2x is -1/2x. There is only one option with this slope. If you're still not sure then you can use a graphing calculator to check this. An online one would be desmos
Answer:
Part 1) The vertex is the point (0.50,2.50)
part 2) 
Step-by-step explanation:
we have

Part 1) Convert into vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side



-----> equation in vertex form
The vertex is the point (0.50,2.50)
Part 2) Find the value of y for x=6
substitute the value of x in the equation



Answer:

Step-by-step explanation:
We want use the order of operations and the digits 2, 4, 6, and 8 to create an expression with a value 2.
The expression is:

The order of operations is PEDMAS
Deal with parenthesis first,

Next deal with exponent

No Division and Multiplication so skip to Addition.

Finally subtract to get:

I think it is 20x + 72 I think that’s right!!
