1.The equation of line CD is (y−3) = − 2 (x − 4). What is the slope of a line perpendicular to line CD? 2.The equation of line A
gogolik [260]
So here's how to do it,
slope intercept form is y=mx+b
m is the slope, b is the y- intercept, X is your unknown variable.

you need to solve to get y by its self to get your slope.

for perpendicular lines flip the slope

ex 1, smy=2x+6 --- slope of a perpendicular line will be 1/2

ex 2, y=3/2+8 ---8 perpendicular lien would have a slope of 2/3

parallel lines have the same slope so any equation with with the same slope will be parallel if it has the same degree.

ex. y=2x+14 is parallel to y= 2x+56

slope can be found using the following formula if you have two sets of points on the same line

m= y2-y1 ÷ X2 - X1

On a recent day, 8 euros were worth $11 and 24 euros were worth $33. Enter an equation of the form y = kx to show the relationsh
irakobra [83]

Put the numbers in the given equation and solve for k.

... $11 = k·(8 €)

Divide by the coefficient of k:

... k = $11/(8 €) = 1.375 $/€

Then your equation is ...

... y = (1.375 $/€)x

_____

It is fairly common to leave the units out of such equations, assuming that everyone understands that x is in euros and y is in dollars and the conversion factor includes a unit change from euros to dollars. Thus, you might expect to see ...

... y = 1.375·x
