line k has a slop of -5. Line J is perpendicular to line K and passes through the point (5,9). Create the equation for line j.

sveticcg [70]

Answer:

The equation of the line would be y = 1/5x + 8

Step-by-step explanation:

Since the slope of k is -5, the slope of j has to be 1/5. This is because perpendicular lines have opposite and reciprocal slopes.

Now we can use the slope and the point in point-slope form to get the equation.

y - y1 = m(x - x1)

y - 9 = 1/5(x - 5)

y - 9 = 1/5x - 1

y = 1/5x + 8

chubhunter [2.5K]

Answer:

13/100

Step-by-step explanation:

we know that

The probability of the event occurring plus the probability of the event not occurring must equal to 1

If the probability that a pupil in a class has a calculator is 0.87

then

The probability that the pupil does not have a calculator is equal to

$1-0.87=0.13$

Convert to fraction

$0.13=\frac{13}{100}$
