Help me please lol. Timed test

y=1/2x-7

Step-by-step explanation:

We know the slope is 1/2, and the equation for a linear equation is y=mx+b, but we can substitute m for 1/2 as that is the slope.

Doing this we get y=1/2+b, and now we can plug in the x and y values given, and solve for b to get the equation.

Plugging in we get:

-9=-4(1/2)+b

-9=-2+b

-7=b

This means the equation is y=1/2x-7, or the first option.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

because they could drop even lower..
