identify the equation of a line in slope-intercept form that is perpendicular to y = -1/3 x + 2 and passes through (2, 10)
1 answer:
Answer:
Step-by-step explanation:
y = -1/3x + 2
m1 = -1/3
Slope of the perpendicular line = -1/m1 = -1 ÷
= 
Equation of the required line : y = mx +b
y = 3x + b
Plugin x = 2 and y 10 in the above equation
10 = 3*2+ b
10 = 6 +b
10 - 6 = b
b = 4
Equation: y = 3x + 4

Answer:
100 people
Step-by-step explanation:
if u notice the points are (2,6) and (6,18). 6÷2=3 and 18÷6=3, so if you catch this pattern than you can do 300÷3=100
Answer:
32
Step-by-step explanation:
So the order of the points is: GHJK
GH = x+10 =JK
HJ=8
JK=2x-4
JK = x+10=2x-4
x+10=2x-4
10+4=2x-x
x=14
GH= 14+10 =24
GJ = GH +HJ = 24+ 8=32
Direct variation means their ratio is a constant
x/y is 9/45=1/5
so when x=2, y=5*2=10
