What ii the midterm was today?

Front

What is the formula to find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

Find the slope of the line that passes through the points (6,7) and (4,2).

Back

The slope is 5/2.

Front

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

Back

The slope-intercept form is given by y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you solve for h in the equation S = 2πrh?

Back

h = S / (2πr).

Front

What does the equation d = rt represent?

Back

This equation represents the relationship between distance (d), rate (r), and time (t).

Front

How do you solve for r in the equation d = rt?

Back

r = d / t.

Front

What is the slope of a line that is decreasing?

Back

The slope of a decreasing line is negative.

Front

Write the slope-intercept form of the equation of a line that passes through the point (-1, 4) with a slope of -3.

Back

y = -3x + 1.

Front

What is the significance of the y-intercept 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 the slope of a line is 0, what does that indicate about the line?

Back

A slope of 0 indicates that the line is horizontal.
