Question

which equation have a graph that is perpendicular to the graph 4x-2y=1? a.) y=-2x+8 b.)6x-3y=9 c.)2x+4y=-1

Answer 1

c. 2x+4y=-1

Answer 2

When you put the initial graph in point-slope form, the slope is 2. Since the perpendicular line will have a slope that is the negative reciprocal, the slope needs to be (-1/2). When in point-slope form, the last one is the only one that fits this
