Writing Linear Equations from Points and Slopes

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

• y = mx + b

• ax + by = c

• x = my + b

• y - y1 = m(x - x1)

Given a slope of 2 and a y-intercept of -3, what is the linear equation in slope-intercept form?

• y = 2x - 3

• y = -2x - 3

• y = 2x + 3

• y = -2x + 3

How do you find the slope between two points (1, 3) and (3, 7)?

• (7 - 3) / (3 - 1)

• (3 - 1) / (7 - 3)

• (3 - 7) / (1 - 3)

• (7 - 1) / (3 - 3)

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

• y - y1 = m(x - x1)

• ax + by = c

• y = mx + b

• x = my + b

Convert the equation y = 2x - 2 + 3 to standard form.

• 2x - y = 1

• -2x + y = 1

• 2x + y = 1

• -2x - y = 1

Given points (-2, 1) and (3, 16), what is the slope of the line?

• 2

• 4

• 5

• 3

What is the y-intercept of the line passing through the points (3, 16) with a slope of 3?

• 7

• 9

• 5

• 3

How do you find the slope from a graph?

• Sum of y-values divided by sum of x-values

• Sum of x-values divided by sum of y-values

• Change in x-values divided by change in y-values

• Change in y-values divided by change in x-values

Given a graph with a y-intercept of -3 and a slope of 3/4, what is the equation in slope-intercept form?

• y = 3/4x - 3

• y = 3/4x + 3

• y = -3/4x - 3

• y = -3/4x + 3

Given points (5, 3) and (7, 7) from a data table, what is the slope of the line?

• 3

• 2

• 4

• 1
