Answer: y - 9 = 2(x - 5)

Step-by-step explanation:

Point slope form: y - y1 = m(x - x1)

substitute 5 for x1 and 9 for y1 and 2 for m

x1 = 5

y1 = 9

m = 2

you get y - 9 = 2(x - 5)

Answer:

y-9=2(x-5)

Step-by-step explanation:

The equation for point slope is y-y_1=m(2-x_1)

we are given all those things already

(5,9) = (x_1,y_1)

Slope 2 = m

Just plug those in and get y-9=2(x-5)

Write an equation of a line in slope-intercept form with the given slope and y-intercept.
Nostrana [21]

Answer:

<em>y</em> = -6<em>x - </em>2

<em>y </em>= <em>x</em> - 12

Step-by-step explanation:

Slope-intercept equation for line of slope <em>m</em> and <em>y</em>-intercept <em>b</em>:

<em>y</em> = <em>mx </em>+ <em>b</em>

A. <em>m</em> = -6, <em>b</em> = -2

<em>y</em> = -6<em>x - </em>2

B. <em>m</em> = 1, <em>b </em>= -12

<em>y </em>= <em>x</em> - 12

A jar contains 4 blue, 11 pink, 5 red, and 6 orange jellybeans. Once is selected, replaced, then another is selected. Find P(blu
faltersainse [42]

Answer:

P(blue then red)=5/169

Step-by-step explanation:

the probability of picking the blue is 4/26 it's replaced so the total jellybeans doesn't change therefore the sample space doesn't change. the probability of picking a red is 5/26

to find the probability of picking them in that order, you multiply the two together

(4/26)x(5/26)=20/676

reducing that we get:

P(blue then red)=5/169
