Exploring Slope-Intercept Form of Linear Equations

What is the formula for slope intercept form?

• y = mx + b

• y = bx + m

• y = b/m + x

• y = m/b + x

What does 'm' represent in the slope intercept form?

• Y-intercept

• X-intercept

• Slope

• Coordinate

What does the 'b' value represent in the slope intercept form?

• The y-intercept

• The slope

• The x-intercept

• The coordinate

If a line has a slope of 2 and a y-intercept of 6, what is its equation?

• y = 6x - 2

• y = 2x - 6

• y = 6x + 2

• y = 2x + 6

How do you find the y-intercept when given a slope and a point on the line?

• Substitute the slope and point values into y = mx + b and solve for b

• Multiply the slope with the x-value of the point

• Add the slope to the y-value of the point

• Divide the y-value of the point by the slope

What is the equation of a line with a slope of 3 passing through the point (-1, 6)?

• y = -3x + 9

• y = 3x + 9

• y = 3x - 9

• y = 9x + 3

How do you calculate the slope given two points?

• (y2 - y1) / (x2 - x1)

• (x2 - x1) / (y2 - y1)

• (y2 + y1) / (x2 + x1)

• (x2 + x1) / (y2 + y1)

What is the slope of a line passing through the points (-1, 5) and (3, -3)?

• -1/2

• 1/2

• 2

• -2

After finding the slope using two points, what is the next step to find the equation of the line?

• Substitute the slope into y = mx + b along with one of the points to solve for b

• Multiply the slope by the x-value of one of the points

• Calculate the midpoint of the two points

• Find the x-intercept of the line

What is the equation of a line that goes through the points (-1, 5) and (3, -3)?

• y = 2x + 3

• y = -2x - 3

• y = 2x - 3

• y = -2x + 3
