What Is the y-intercept of the two points that cross through (8,1) and (-3,1)?
kramer

Answer:

(0,1)

Step-by-step explanation:

The line made by these two points is perfectly horizontal since the value of y in both points is the same. When the y value is the same in all given points, that number is also the y-intercept and the line doesn't cross the x axis.

(The opposite applies as well: If the x value is the same in all given points, that number is also the x-intercept and the line doesn't cross the y axis. In that case, that means the line is vertical)

Please help me with question 2
WARRIOR [948]

Answer:

sin(-a)= -15 /17

Step-by-step explanation:

Alright, lets remember that sin(x) is odd function, which means that

wherever you watch an expression like this: sin(-a), you can use the odd functions property, and turn it like the following

sin(-a)= - sin(a)

Now, other thing to remember: (sin(x))^{2}+(cos(x))^{2}=1

So, we can obtain any value for sin(x) function starting from the opposite function, cos(x), using the following:

sin(x)=\sqrt{1-(cos(x))^{2} }

So, if cos(a)= - 8 / 17, using the above equation we obtain the value for sin(a)

sin(a)=\sqrt{1 - (cos(a))^{2} } = \sqrt{1 - ( \frac{8}{17} )^{2}  }= \sqrt{\frac{225}{289} }  =15/17

Using the odd function property, we get the following result

sin(-a)= - sin(a) = -15/17
