Answer:

y = -1

Step-by-step explanation:

We Know:

y = 2x + 1, and x= -1.

Substitute:

y = 2(-1) + 1

Multiply:

2 * -1 = -2

y = -2 + 1

Add:

-2 + 1 = -1

So,

y = -1.

Y = 2x + 1
y = 2(-1) + 1
y= -2 + 1
y= -1

Given H (6,7) and I (-7,6), if point G lies 1/2 of along the way HI, Santiago Argues That Point G Is Located At The Origin. Is S

Yuliya22 [10]

Santiago was incorrect, as the point $G$ is located at $(-\frac{1}{2}, \frac{1}{2})$

Explanation

The co ordinates of the given points are: $H(6,7)$ and $I(-7,-6)$

If point $G$ lies $\frac{1}{2}$ of along the way $\overline{HI}$ , that means $G$ should be the midpoint of line $\overline{HI}$ .

Mid-point formula is: $(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})$ , where $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ are two endpoints.

So, the co ordinate of the midpoint of $H$ and $I$ will be......

$(\frac{6+(-7)}{2},\frac{7+(-6)}{2})\\ \\ =(-\frac{1}{2}, \frac{1}{2})$

Co ordinate of the origin is always $(0,0)$

So, Santiago was incorrect, as the point $G$ is located at $(-\frac{1}{2}, \frac{1}{2})$
