an equation of a line in slope intercept form with slope -3 going through the point (2, - 2).

Question

how to do an equation of a line in slope intercept form with slope -3 going through the point (2, - 2).

Answer 1

strate line, slope=-3, thru point=(2,-2)

y=-3x+konst

tu get y-intersept, extend line bak from (2,-2)

deltax=-2, so deltay=(-2)*(-3)=+6

yintersept=-2+6=4

y=3x+4

Answer 2

y=-3x +4
