Write an equation of the line that passes through the point (–1, 4) with slope 2. A. y+1=−2(x−4) B. y+1=2(x−4) C. y−4=2(x+1) D.

In-s [12.5K]

Answer:

$y-4=2\,(x+1)$

which agrees with answer C in your list of possible answers.

Step-by-step explanation:

We can use the general point-slope form of a line of slope m and going through the point $(x_0, y_0)$ :

$y-y_0=m(x-x_0)$

which in our case, given the info on the slope (2) and the point (-1, 4) becomes:

$y-y_0=m\,(x-x_0)\\y-4=2\,(x-(-1))\\y-4=2\,(x+1)$

factor the expression below x^2+16x+64 a) (x-4)(x-16) b) (x-8) (x-8) c) (x+8) (x+8) d) (x+4) (x+16)

professor190 [17]

A) (x-4)(x-16)=x^2-16x-4x+64=x^2-20x+64
b) (x-8)(x-8)=x^2-16x+64
c) (x+8)(x+8)=x^2+16x+64
d) (x+4)(x+16)=x^2+20x+64
The given expression is x^2+16x+64, it is same as c)
The final answer is c) (x+8)(x+8)
