First we find the slope between the two given points.

m = (y2 - y1)/(x2 - x1) = (-5 - 2)/(7 - 6) = -7/1 = -7

Now we use the slope-intercept equation of a line.

y = mx + b

We use one point as x and y, and we solve for b.

2 = -7(6) + b

2 = -42 + b

b = 44

The equation is

y = -7x + 44

Answer: f(x) = -7x + 44

BRAINLIEST Multiply each side by the common denominator​
Dovator [93]

Answer:

c. x² + 2x -5 = 0

Step-by-step explanation:

 Given expression;

         \frac{5}{x}   = \frac{x + 2}{3}  

Unknown:

 The quadratic equation equivalent to this expression:

Solution:

  The common denominator here is 3x;

 

    So, multiply both sides by 3x

          \frac{5}{x} x 3x  =  \frac{x + 2}{3} x 3x

          5 x 3 = (x + 2)x

           15 = x² + 2x

     So;

          x² + 2x - 15

The quadratic expression is x² + 2x - 15
