g is among them). Assuming that the singers are equally likely to pick any song and no song repeats, what is the probability that your favorite song is one of the 20 that you hear that night?

Find the equation of the line that passes through the points (-3,0) and (4,2). Using point slope formula
astra-53 [7]

Answer:

\large\boxed{y-0=\dfrac{2}{7}(x+3)}\\\downarrow\\\boxed{y=\dfrac{2}{7}x+\dfrac{6}{7}}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

<em>m</em><em> - slopei</em>

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

======================================

We have the points (-3, 0) and (4, 2).

Substitute:

m=\dfrac{2-0}{4-(-3)}=\dfrac{2}{7}

Put the value of the slope and the coordinates of the point (-3, 0) to the equation:

y-0=\dfrac{2}{7}(x-(-3))

y-0=\dfrac{2}{7}(x+3)

Converto to the slope-intercept form (<em>y = mx + b</em>):

y=\dfrac{2}{7}x+\dfrac{6}{7}
