Answer:
3/7
Step-by-step explanation:
y-mx+b is the format
in this equation, 3/7 is m, and 9 is b
m is the slope
therefore, 3/7 is the slope
Answer:
The first term is 12. The common difference is 4.
Step-by-step explanation:
The difference between the third and seventh terms is
36 - 20 = 16
The 7th term is the 4th term after the 3rd term, so the common difference is
16/4 = 4
Answer: The first term is 12. The common difference is 4.
Answer:you go up one over three
Step-by-step explanation:
70) perpendicular means you take the number in from of the x and flip it and switch the sign. that number will become your slope (m).
y=mx+b. plug in slope and point
-5=(7/9)(-4)+b. multiply
-5=(-28/9)+b. add over -28/9
b= -17/9. plug b and slope into original equation
y=(7/9)x+(-17/9) get rid of frac by multi by 9
(y=(7/9)x+(-17/9))*9
9y=7x+-17. subtract over 7x
-7x+9y=-17. answer
Same goes for the rest. number 72 the perp slope will be (1/3) and for 74 the answer will be x=-5 (that is a weird case)
All of these answers are right
