Slope =0
Answer:
1/10
Step-by-step explanation:
slope of a line is m
m=y2-y1/x2-x1 = 3-2/6-(-4)= 1/10
Answer:
x=19, DE=84, EF=36
Step-by-step explanation:
Since the total value of DF is 120, DE and EF must add up to 120. Therefore:
4x+8+2x-2=120
Combine like terms:
6x+6=120
Divide both sides by 6:
x+1=20
Subtract 1 from both sides:
x=19
This means that DE is 4(19)+8=84, and EF is 2(19)-2=36.
Hope this helps!
Answer:
1. no solution
2. one solution
3. infinitely many solutions
4. one solution
Step-by-step explanation:
1. same slope, different intercepts, parallel lines, no solution
2. different slopes, lines intersect at 1 point, one solution
3. same equation, infinitely many solutions
4. different slopes, lines intersect at 1 point, one solution
