If M is the midpoint of JK then JM+MK=JK and JM=MK
so
6x-7=2x+3
minus 2x both sides
4x-7=3
add 7 both sides
4x=10
divide both sides by 4
sub back
JM=6x-7
JM=8
JM=MK=8
JM+MK=8+8=16=JK
and JM=8=MK and JK=16
so
6x-7=2x+3
minus 2x both sides
4x-7=3
add 7 both sides
4x=10
divide both sides by 4
sub back
JM=6x-7
JM=8
JM=MK=8
JM+MK=8+8=16=JK
Answer:
Step-by-step explanation:
First, find the slope using the points (3, 2) and (-1, -1):
Slope =
Find the y-intercept, b, by substituting x = -1, y = -1 and m = ¾ in y = mx + b.
-1 = ¾(-1) + b
-1 = -¾ + b
Add ¾ to both sides
-1 + ¾ = b
(-4 + 3)/4 = b
-¼ = b
Substitute m = ¾ and b = -¼ in y = mx + b.
The equation would be:
