Answer:

B) $\frac{-5}{4}$

Step-by-step explanation:

Take any two points

(x₁ , y₁) = ( -4 , 0) & (x₂ , y₂) = (0 , -5)

$slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$=\frac{-5-0}{0-[-4]}\\\\=\frac{-5}{0+4}\\\\=\frac{-5}{4}$

wrote an equation for the line. passing through (-5,7) and parallel to the line whise equation is 5x-3y-4=0

xeze [42]

Step-by-step explanation:

5x-3y-4=0---------(1)

Slope = - coefficient of X/ coefficient of y

= -5/(-3)

= 5/3

(x1,y1)= (-5,7)

Equation of the line,

Y-Y1= slope(X-X1)

Y-7= (5/3)×(X-(-5))

Y-7= (5x+25)/3

3y-7=5x+25

5x-3y+32=0 is the required eqn
