Understanding Slope-Intercept Form

What does the term 'linear' in linear equations imply?

• It refers to a triangle.

• It refers to a circle.

• It refers to a line.

• It refers to a square.

Which form of linear equation is represented by y = mx + b?

• Point-slope form

• Slope-intercept form

• Standard form

• Quadratic form

If the slope is 2 and the y-intercept is -1, what is the equation of the line?

• y = -2x - 1

• y = 2x - 1

• y = -2x + 1

• y = 2x + 1

How do you find the slope from a graph?

• Count the number of points on the line.

• Find the midpoint of the line.

• Count the boxes up and over between two points.

• Measure the angle of the line.

What is the y-intercept if a line crosses the y-axis at 7?

• 7

• 1

• -7

• 0
