Answer:
y = - 2x + 8
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 
x - 9 ← is in slope- intercept form
with m =
given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= - 2
y = - 2x + c ← is the partial equation
to find c substitute (3, 2 ) into the partial equation
2 = - 6 + c ⇒ c = 2 + 6 = 8
y = - 2x + 8 ← equation of perpendicular line
Answer:
Step-by-step explanation:
the two given lines are parallel.
Hence they do not intersect.
or they have no solution.
256 km.. you take 32 and mulitply it by 8 and get 256. since the bus can go 32 km in half an hour in four hours it would go 8 times that distance.
Answer:
7, -2
Step-by-step explanation:
we call the first number "X" and the second one "Y"
X is 9 more than Y! which means we need to add 9 to Y so it'll be equal to X. so: Y+9=X
also 2×(X+Y)=10
you can also write this down as: 2X+2Y=10
now we have:
X=Y+9
2X+2Y=10
you can now put what equals to X in the second Equation:
2(Y+9)+2Y=10 => 2Y+18+2Y=10 => 4Y=10-18 =>Y= -2
the only thing left to do is to put Y= -2 in the first equation:
X= -2+9 => X=7
