write an equation in the point-slope form and the slope-intercept form.
slope=-5, passing through (-4, -2)
:
The point-slope formula is highlight%28y-y1=m%28x-x1%29%29 where m=slope and (x1,y1) is the given point:
y-%28-2%29=-5%28x-%28-4%29%29
y%2B2=-5%28x%2B4%29 <--Point-slope form
:
The slope intercept form is highlight%28y=mx%2Bb%29, where m=slope and (0,b)=y-intercept. We take the point-slope form and solve it for y.
y%2B2=-5%28x%2B4%29
y%2B2=-5x-20
y%2B2-2=-5x-20-2
y=-5x-22 <---slope-intercept form
Happy Calculating!!!
