Perpendicular means that it has a slope that is the reciprocal of the original, and parallel means that the slopes are the same.
1)Parallel means they have to have the same slope. Since our equation is y=2/3x+1, a line parallel to that would be(using out points) -5=2/3(-4)+b.
To find the y-intercept, solve for "b".
b=-7/3
Our equation would then be y=2/3x-7/3
2)Perpendicular lines have opposite-reciprocal slopes. our previous equation was y=2/3x+1, so our new equation would be -5=-3/2(-4)+b. Now lets solve for b.
b=-11
So our perpendicular equation would be y=-3/2x-11

Answer:
A
Step-by-step explanation:
Im pretty sure its A because
55ish plus 15ish equals 70 which is their ages combined
55-60 is also 4 x 15
5 cups.
To go from 1/2 to 2 cups of raisins you multiply by 4.
So 1 1/4 is really 5/4. That times 4 is 20/4 which is 5.
