Linear Equations

What is a linear equation?

• An equation that traps to be a V.

• An equation that graphs to be a parabola.

• An equation that graphs to be a line.

• An equation that describes a constant slope.

What is the basic equation for a linear equation?

• Y= |x|

• f(x) = y

• f(x) = x

• y =x

What form is slope- intercept form?

• ax + by= c

• y = mx + b

• y - y1 = m(x - x1)

• y = a|x - h| + k

Which of the following is not a form for a linear equation?

• ax + by= c

• y = mx + b

• y - y1 = m(x - x1)

• y = a|x - h| + k

What form is point-slope form?

• ax + by= c

• y = mx + b

• y - y1 = m(x - x1)

• y = a|x - h| + k

What form is standard form?

• ax + by= c

• y = mx + b

• y - y1 = m(x - x1)

• y = a|x - h| + k

In the equation y = mx + b, what does the m represent ?

• X- intercept

• Y-intercept

• Slope

• Shading

What is true of all horizontal lines?

• The slope is undefined

• The slope is zero

• It does not have an x- intercept

• It’s equation is always y = k

What is true of all vertical lines?

• The slope is undefined

• The slope is zero

• It does not have an y-intercept

• It’s equation is always x = k

In order to find the x- intercept, you ————

• Have to graph the equation

• You let y = 0

• You let x= 0

• You copy off of your neighbor
