Writing Linear Equations in Point-Slope Form from Graphs

Which form of a linear equation is represented by ax + by = c?

• Quadratic form

• Standard form

• Point-slope form

• Slope-intercept form

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

• y - y1 = m(x - x1)

• x = my + b

• ax + by = c

• y = mx + b

How do you identify the slope from a graph?

• By finding the X-intercept

• By finding the Y-intercept and another point

• By using the equation y = mx + b

• By counting the number of squares

If the Y-intercept is 4 and you move up 3 units and right 2 units, what is the slope?

• 4/3

• 2/3

• 3/2

• 1/2

What are the coordinates of a point if you trace it down to the X-axis and it is 2, and trace it to the Y-axis and it is 7?

• (2, 7)

• (2, -7)

• (7, 2)

• (-2, 7)

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

• x = my + b

• y - y1 = m(x - x1)

• ax + by = c

• y = mx + b

In the point-slope form y - y1 = m(x - x1), what does y1 represent?

• The Y-intercept

• The X-coordinate of the point

• The slope

• The Y-coordinate of the point

How do you handle a negative coordinate in the point-slope form?

• Subtract the negative number

• Add the negative number

• Multiply by -1

• Ignore the negative sign

What is the result of subtracting a negative number?

• A negative number

• Zero

• A positive number

• The same number

What is the first step in writing a point-slope equation from a graph?

• Choose a point on the line

• Find the Y-intercept

• Write the equation

• Identify the slope
