Q2 Benchmark Review AFDA (Set #2)

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented as 'm' in the equation of a line (y = mx + b). It is calculated as the change in y divided by the change in x (rise/run).

Front

How do you determine the slope from a graph?

Back

To determine the slope from a graph, select two points on the line, calculate the vertical change (rise) and the horizontal change (run) between these points, and then divide the rise by the run.

Front

What is a y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented as 'b' in the slope-intercept form of a line (y = mx + b).

Front

How do you find the y-intercept from a graph?

Back

To find the y-intercept from a graph, look for the point where the line intersects the y-axis. The y-coordinate of this point is the y-intercept.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution to the system is the point(s) where the equations intersect.

Front

What does it mean to solve a system of equations graphically?

Back

Solving a system of equations graphically means plotting the equations on a graph and identifying the point(s) where the lines intersect, which represents the solution.

Front

What is the product of a number and a constant?

Back

The product of a number (m) and a constant (6) is expressed as 6m, which means 6 times the value of m.

Front

How do you express 'm plus the product of 6 and n'?

Back

This expression is written as m + 6n, indicating that you add m to the product of 6 and n.

Front

What is the formula for slope-intercept form?

Back

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, meaning the line rises from left to right.
