Midpoint = (x1 + x2) / 2, (y1 + y2)/2
(-2,1)....x1 = -2 and y1 = 1
(4,-1)...x2 = 4 and y2 = -1
time to sub
m = (-2 + 4) / 2 , (1 + (-1) / 2
m = (2/2), (0/2)
m = (1,0) <==

y = -x + 1.....(1,0)...x = 1 and y = 0
0 = -1 + 1
0 = 0 (correct)

so the midpoint M (1,0) lies on the line since its coordinates satisfy the equation <===

2x+4y=1<br> 3x-5y=7 <br> solve the simultaneous equations

WITCHER [35]

Answer:

y= -1/2

x=3/2

Step-by-step explanation:

first isolate x

2x+4y=1

2x=1-4y

x=(1-4y)/2

subsitute it in the second equation

look at the pic

What are the intercepts for the equation? Select all that apply. x + y = 4 *

olchik [2.2K]

Answer:

y intercept (0, 4)

x intercept (4, 0)

I hope this is good enough:
