Work Step by Step

The equation y=3x+2 is in point slope form, where 3 is the slope of the line. If the other edge of the sidewalk is parallel, then the line representing that edge as the same slope. Responses F and G can be eliminated because the coefficient of x is not 3. Substitute the values from the given point (3,4) into the equations in responses H and I. The equation that is true is the correct response. H) $y=3x-9$ $4\overset?=3(3)-9$ $4\overset?=9-9$ $4\overset?=0\ X$ I) $y=3x-5$ $4\overset?=3(3)-5$ $4\overset?=9-5$ $4\overset?=4\checkmark$
