9. Use the diagram below to answer #9-12. Given Triangle GHI with G(7, 0), H (-5, 5) and I (1, 9), find the midpoint of HI.

1 answer:

3 0

Midpoint formula : (x1 + x2) / 2, (y1 + y2) / 2
(-5,5)....x1 = -5 and y1 = 5
(1,9).....x2 = 1 and y2 = 9
now we sub
m = (-5 + 1) / 2, (5 + 9) / 2
m = -4/2, 14/2
m = (-2,7) <=== ur midpoint of HI

Graph. y−2=23(x+4) Use the Line Tool and select two points to graph the equation. Use the slope and the point provided in the eq

sveticcg [70]

Answer:

See attached picture.

Step-by-step explanation:

The equation is in point slope form $y - y_1 = m(x-x_1)$ where m is the slope and $(x_1,y_1)$ is a point.

For the equation y-2 = 23(x+4), graph the point (-4,2). Then from this point count up 23 and over to the right 1.

This is the graph of the line.
