Answer:
y = 5x - 56
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
Here m = 5, thus
y = 5x + c ← is the partial equation of the line
To find c substitute (8, - 16) into the partial equation
- 16 = 40 + c ⇒ c = - 16 - 40 = - 56
y = 5x - 56 ← equation of line
