Question

Equation through the point (5,9) with a slope of -4

Answer 1

The answer is: y=-4x+29

To solve this, you need to know the y-intercept. 
1. y=-4x+b
2. 9+-4(5)+b
3. 9=-20+b
4. b=9+20
5. b=29
6. Substitute into y=-4x+b

Answer 2

Y-9=-4(x-5) Remove the () y-9=-4x+5 Simplify the equation by adding 9 to each side. y=-4x+14 (I used the point slope form and turned it into slope intercept form).
