Graphing Lines from Non-Slope Intercept Equations

What is the standard form of a linear equation?

• ax + by = c

• y = mx + b

• ax + c = by

• x = my + b

What is the first step in converting an equation to slope-intercept form?

• Multiply both sides by x

• Solve for y

• Add y to both sides

• Subtract x from both sides

If an equation is in the form y = 5x + 3, what is the slope?

• 1/5

• 3

• 0

• 5

How do you graph the y-intercept of an equation?

• Plot the point where the line crosses the x-axis

• Plot the point where the slope is zero

• Plot the point where x equals zero

• Plot the point where the line crosses the y-axis

What does a negative slope indicate about the direction of a line?

• The line is horizontal

• The line goes down from left to right

• The line goes up from left to right

• The line is vertical

How do you handle a negative coefficient when solving for y?

• Multiply by the negative coefficient

• Divide by the negative coefficient

• Add the negative coefficient to both sides

• Ignore the negative sign

What is the slope of the equation y = 3/2x - 6?

• -6

• 2/3

• 6

• 3/2

If an equation has no number added to x, what is the y-intercept?

• y

• x

• 0

• 1

What is the slope of the equation y = 2x?

• 2

• 0

• 1/2

• x

What is the final step in graphing a line after finding the slope and y-intercept?

• Subtract the slope from the y-intercept

• Multiply the slope by the y-intercept

• Connect the points

• Divide the slope by the y-intercept
