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
Hope that was helpful. :)
Answer
D.
Step-by-step explanation:
48/4=12
$12 for 1 adult
10-4=6
42/6=7
$7 for 1 child
The slope of this line can be described as D. zero slope because there is no upward movement, so there is no slope, so it is zero.
Answer: D. zero slope
x+y =15
x-y = 3
add the two equations
2x = 18
divide by 2
x = 9
x + y = 15
9 + y =15
subtract 9
y = 9
The two numbers are 6 and 9
