Y=-3+6and y=1/3x-8 determine if the equation are parallel, perpendicular or neither

Slope intercept form: y = mx + b

m = slope and b = y-intercept

The equation is: y = -3x + 6

The m value for this is -3, so the line has a slope of -3. If y = 1/3x - 8 was parallel to y = -3x + 6 then they would have the same slope, which they do not. So they aren't parallel.

The find the slope of a perpendicular line, take the negative reciprocal of the slope of y = -3x + 6. The negative reciprocal of -3 is 1/3.  y = 1/3x - 8 has a slope of 1/3, so they are perpendicular to each other.

investment b is an ordinary annuity with $3,909.64 in the account after one year.

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
