1st semester algebra 1 Review

Front

For f(x) = -5x + 4, what is the value of x for which f(x) = 29?

Back

x = -5

Front

Write the equation of a line given its slope and a point on the line.

Back

Use the point-slope form: y - y1 = m(x - x1).

Front

Given f(x) = 7x - 2, find f(x) when x = -3.

Back

f(-3) = -23

Front

Which graph matches the inequality -2 ≥ n?

Back

Graph A shows the correct representation.

Front

Find the slope of the line for the equation 3x + 5y = 15.

Back

m = -3/5

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 y-intercept of a linear equation?

Back

Set x = 0 and solve for y.

Front

What does it mean for a function to be linear?

Back

A linear function has a constant rate of change and can be graphed as a straight line.

Front

What is the definition of a function?

Back

A relation where each input has exactly one output.

Front

How do you determine if a relation is a function?

Back

Use the vertical line test: if a vertical line intersects the graph more than once, it is not a function.
