What is the equation of the line in slope-intercept form?

y = 2x

Step-by-step explanation:

( 0 , 0 ) ( 10 , 20)

Slope = Change in y ÷ change in x

m= 2; (0,0)

y - y1 =m(x - x1)

y - 0 = 2(x - 0)

    y = 2x

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
