math midterm

QuestionAnswer
liner equation in slope intercept form y=mx+b m=slope y=y-intercept
point-slope intercept form y-y1= m(x-x1)
SOMP break down S-slope O-opposite reciprocal M-midpoint P-point-slope intercept form
standard form Ax+By=C
parallel same slope
perpendicular opposite reciprocal slope
What is the equation of the x-axis? y=0
what is the equation of the y-axis x=0
relationship between parallel lines non intersecting lines that are always the same distance apart and the same slope
relationship between perpendicular lines their slopes are negative reciprocals of each other
distance formula sqrt (x2-x1)2 + (y2-y1)
colinear all lie on the same line
line series of lines that extend in opposite directions have arrows at the ends
line segment part of line consisting of two endpoints no arrows
congruent line segments segments of the same length
midpoint formula x1+x2/2, y1+y2/2
when do we use the distance formula perimeter of square length of segment determining if 2 segs are congruent
bisector a line or segment that divides a segment into two congruent lines
when writing an equation of a perpendicular bisectors, you must use SOMP
equation of a horizontal line y=#
equation of a vertical line x=#

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
