Intro to Linear Algebra Flashcards
1
Q
slope-intercept eqn
A
y= mx+ c
where m = slope
c = y-intercept
2
Q
standard form eqn
A
Ax + By = C
x, y = variables
A,B,C = co-effiecients
3
Q
point-slope form eqn
A
Y-Y1 = m(X-X1)
m = slope
X1, Y1 = points
4
Q
what is x-intercept?
A
any point where the value of y = o
P(3,0)
x = 3
y = 0
5
Q
what is y-intercept?
A
any point where the value of x = 0
P(0,3)
x = 0
y = 3
6
Q
how do we get m(slope)?
A
slope = rise/run
rise (vertical)
run (horizontal)
7
Q
x-axis?
A
horizontal
8
Q
y-axis?
A
vertical
9
Q
what is a linear equation?
A
an algebraic eqn in which each term has an exponent of one and the graphing of the eqn resuts in a straight line
