How can you write an equation of a line when you are given the slope and a point on the line? Explain

y = mx + b

m = slope b = y-intercept

Step-by-step explanation:

Say you are given 2 and (-1, 4)

the equation will look like this:

y = 2x + b

Now we fill in the x and y:

4 = 2 (-1) + b

Now we just solve it:

4 = 2 (-1) +b

4 = -2 + b

b = 6

b mark me branliest thx

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
