9x+35=-5y slope intercept form

german

Answer:

y = - $\frac{9}{5}$ x - 7

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 )

Given

9x + 35 = - 5y ( add 5y to both sides )

5y + 9x + 35 = 0 ( subtract 9x + 35 from both sides )

5y = - 9x - 35 ( divide all terms by 5 )

y = - $\frac{9}{5}$ x - 7 ← in slope- intercept form
