70 you solve by making a proportion 2.8/x =4/100
Additive inverses combine to get 0. So, k is -1.4. The sum is 0. Hopefully that will help.
Slope can be calculated using the formula: m=
y1/x1 represents the first number in the bracket
y2/x2 represents the second number in the bracket
Calculation
m =
m =
m= 6/-12
m= -0.5 or -1/2
Therefore, the answer is B.
Answer:
the first question would be y= -1/4x + 8
the second one would be 3x + 5y = -65
the third one would be y= -2
and last but not least... the last one would be b.
