Math 8.3 Review: Writing Linear Eq from table, graph & points

Front

Write an equation in slope-intercept form from the points (0, 2) and (1, -3)

Back

y = -5x + 2

Front

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

Back

-4

Front

Which equation best represents the line on the graph? (Options: y= 1/2x, y= -1/2x, y = 2x, y = -2x)

Back

y= 1/2x

Front

Write the equation of a line that contains the point (3, 5) and has a slope of 3 in slope-intercept form.

Back

y = 3x - 4

Front

What is the y-intercept of the line graphed below? (Options: 3, 4, -3, 4/3)

Back

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the change in y divided by the change in x (rise/run).

Front

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

Back

The slope-intercept form is 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 the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the slope-intercept form.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates a horizontal line.
