Alg II Chapter 2 Basics

Front

What does the b represent in y=mx+b?

Back

y-intercept

Front

Move the following problem into standard form: y=14x-4

Back

14x-y=4

Front

Which of these is point-slope form?

Back

y-y₁=m(x-x₁)

Front

What is the equation of the line graphed above? (Assuming the line is horizontal at y=-4)

Back

y=-4

Front

Solve for x and y: 3x + 2y = 16, 7x + y = 19

Back

(2,5)

Front

What is the slope in the equation y=mx+b?

Back

m (the coefficient of x)

Front

What is standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x.

Front

How do you find the y-intercept from the equation y=mx+b?

Back

Set x=0 and solve for y.

Front

What is the difference between slope-intercept form and point-slope form?

Back

Slope-intercept form is y=mx+b; point-slope form is y-y₁=m(x-x₁).
