Answer 1

Answer:

3x + 4y = - 20

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 )

Here m = - $\frac{3}{4}$ , thus

y = - $\frac{3}{4}$ x + c ← is the partial equation

To find c substitute (- 8,  1) into the partial equation

1 = 6 + c ⇒ c = 1 - 6 = - 5

y = - $\frac{3}{4}$ x - 5 ← in slope- intercept form

Multiply through by 4 to clear the fraction

4y = - 3x - 20 ( add 3x to both sides )

3x + 4y = - 20 ← in standard form
