The lines intersect at (-2,2).

Step-by-step explanation:

The line has an y intercept of 1 and a slope of -1/2 so after graphing the both of them thats where they intersect.

Hich of the following are the coordinates of the vertex of y = x2 − 10x + 2?

ANEK [815]

The vertex is in essence the turning point of the parabola y = x² − 10x + 2

the x coordinate of the turning point = $- \frac{b}{2a}$
= $- \frac{-(10)}{2(1)}$
= 5

when x = 5, y = (5)² - 10(5) + 2
= -23

Thus coordinate or vertex is ( 5, -23)

Y = −(x + 4)2 − 7 vertex

ICE Princess25 [194]

Answer:

The vertex (h,k) is (-4,-7).

Step-by-step explanation:

I assume you are looking for the vertex $y=-4(x+4)^2-7$ .

The vertex form of a quadratic is $y=a(x-h)^2+k$ where the vertex is (h,k) and a tells us if the parabola is open down (if a<0) or up (if a>0). a also tells us if it is stretched or compressed.
