Write the equation of the line that passes through (5, 6) and (8, 4) in slope-intercept form.
gavmur [86]

Answer:

Step-by-step explanation:

<h3>Equation of the line in slope- intercept form:</h3>

       \sf \boxed{\bf y = mx +b}

Here, m is the slope and b is the y-intercept

  Find the slope with the given two points.

   \sf \boxed{slope = \dfrac{y_2-y_1}{x_2-x_1}}

             \sf =\dfrac{4-6}{8-5}\\\\=\dfrac{-2}{3}

Slope = -2/3 and choose any one the given points.

Substitute m = -2/3  and (5,6)  in the above equation and find 'b'

      \sf 6 =\dfrac{-2}{3}*5+b\\\\6 =\dfrac{-10}{3}+b\\\\6+\dfrac{10}{3}=b\\\\\dfrac{6*3}{1*3}+\dfrac{10}{3}=b\\\\\dfrac{18}{3}+\dfrac{10}{3}=b\\\\\boxed{b=\dfrac{28}{3}}

Equation of the line:

            y = \dfrac{-2}{3}x + \dfrac{28}{3}

Cell phone plan A costs $70 per month and comes with a free $500 phone. Cell phone plan B costs $50 per month but does not come
DaniilM [7]

Answer:25 months

Step-by-step explanation: Let's make the equations first,

Plan A: 70x   Plan B: 50x+500

Now we make it into an equivalent equation:

70x=50x+500

Then we solve:

70x=50x+500

-50x -50x

20x=500

÷20 ÷20

x=25

To check if it's correct, we just plug it in:

70(25)=50(25)+500

1750=1750
