Apair of equations is shown below.

x + y = 2
y = one halfx + 5

if the two equations are graphed, at what point do the lines representing the two equations intersect?

(4, −2)
(−2, 4)
(2, 5)
(5, −2)

solution is (-2,4)

Step-by-step explanation:

LEts graph both equations.

solve for y

Make a table to graph the equation

x                    y=-x+2

0                     y=2

1                      y=1

Graph the points (0,2) and (1,1) . then extend the line that connects two points

x                    y=(1/2)x+5

0                     y=5

2                      y=6

Graph the points (0,5) and (2,6) . then extend the line that connects two points

The graph is attached below

Both lies intersects at (-2,4)

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

236 cm 16 time 12 = 192

6 times 7 = 42

192+42
