Algebra 1 Review part 1

Front

What is the equation of a line when m = -7 and b = -8?

Back

y = -7x - 8

Front

How would you write the equation with a slope of 2/3 and a y-intercept of -3?

Back

y = 2/3x - 3

Front

Slope is known as rise/

Back

run

Front

Determine the slope and y-intercept from the following equation: 4x + y = -10.

Back

slope: -4, y-intercept: (0, -10)

Front

What is the y-intercept in the following equation: y = -4x - 5?

Back

-5

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls from left to right.

Front

What is the y-intercept of the line represented by the equation y = 3x + 4?

Back

The y-intercept is 4.
