Answer:

y = \frac{1}{2} x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + 2 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-2} = \frac{1}{2}

The line crosses the y- axis at (0, 1) ⇒ c = 1

y = \frac{1}{2} x + 1 ← equation of line

Ken has a toy chest with hot wheels cars. He has 6 camaros, 2 Lamborghinis, 4 corvettes, 8 Ferraris and 12 mustangs. Ken wants t

Lamborghini=
fraction = 2/32
Decimal = 0.0625
Percentage= 6.25%

Corvette=
Fraction= 4/32
Decimal=0.125
Percentage=12.5%



Explanation:


Since the problem says “lamborghini OR corvette” you need to add the probability amount of both cars together. There are 2 lamborghinis and 4 corvettes, so 2+4=6. Now, put this number over the total amount of all cars. 6+2+4+8+12=32. So, the probability will be 6/32 which simplifies to 3/16. In decimal form this is .1875, and in percent form this is 18.75% (move the decimal 2 places to the right)
