You can put this solution on YOUR website!
You can use the Point-Slope form of equation of a line.
Start with the formula for Slope: m=%28y-v%29%2F%28x-u%29 and expect you know the value of m, and you know the point (u,v). Multiply both members by (x-u):

m%28x-u%29=y-v
y-v=m%28x-u%29----------This may be taken as a generalized Point-Slope equation for a line.

Substitute your given values. For your #2, this is how you start:
highlight%28y-%28-1%29=-5%28x-9%29%29
Put this into either Slope-Intercept or Standard Form.
y%2B1=-5x%2B45
highlight%28y=-5x%2B44%29, the slope-intercept form.
