Answer:
y = - 7x - 26
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 = - 7, thus
y = - 7x + c ← is the partial equation of the line
To find c substitute (- 5, 9) into the partial equation
9 = 35 + c ⇒ c = 9 - 35 = - 26
y = - 7x - 26 ← equation of line
