Answer:

y = \frac{2}{3} x + \frac{31}{3}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 8, 5) and (x₂, y₂ ) = (- 2, 9)

m = \frac{9-5}{-2+8} = \frac{4}{6} = \frac{2}{3} , thus

y = \frac{2}{3} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 2, 9 ), then

9 = - \frac{4}{3} + c ⇒ c = 9 + \frac{4}{3} = \frac{31}{3}

y = \frac{2}{3} x + \frac{31}{3} ← equation of line

Evaluate :5/63-(-6/21)​
Mashcka [7]

Answer:

answer is \frac{23}{63}

Step-by-step explanation:

the equation is

\frac{5}{63}-(-\frac{6}{21} )

=> \frac{5}{63}+\frac{6}{21}

=> \frac{5}{63}+\frac{2}{7} ;(divide numerator and denominator of \frac{6}{21} by 3)

=> \frac{5+2*9}{63}

=> \frac{23}{63}

hope you have understood this
