2.2:Linear Equations Flashcards
1
Q
Linear Function
A
A function whose graph is a line
2
Q
Linear Equation
A
y=3x+2
3
Q
Dependent Variable
A
y is called the dependent variable because the value of y depends on the value of x
4
Q
Independent Variable
A
X is called the independent variable
5
Q
Y-intercept
A
The point at which the line crosses the y-axis
6
Q
X-intercept
A
The point at which the line crosses the x-axis
7
Q
Standard Form of a Linear Equation
A
Ax+By=C, where A, B, and C are real numbers, and A and B are not both zero
8
Q
Slope
A
Slope of a non-vertical line is the ratio of the vertical change to a corresponding horizontal change
9
Q
Point- slope form
A
The line through point (x1, y1) with slope m has the equation y-y1=m(x-x1)
10
Q
Slope Intercept Form
A
y=mx+b
