What is the first step in finding the equation of a line given a slope and a point?

• Calculate the y-intercept

• Plot the point on a graph

• Write down the slope

• Solve for x

Given a slope of -2 and a point (1, 6), what is the value of 'b' in the equation y = mx + b?

• 8

• 1

• 6

• -2

What is the equation of the line with a slope of -2 passing through the point (1, 6)?

• y = 2x + 8

• y = 2x + 6

• y = -2x + 8

• y = -2x + 6

Given a slope of 7/3 and a point (3, -5), what is the value of 'b' in the equation y = mx + b?

• -5

• -12

• 3

• 7

What is the equation of the line with a slope of 7/3 passing through the point (3, -5)?

• y = 7/3x + 12

• y = 3/7x - 12

• y = 7/3x - 12

• y = 3/7x + 12

Given a slope of 1/2 and a point (-2, 4), what is the value of 'b' in the equation y = mx + b?

• 1

• -2

• 4

• 5

What is the equation of the line with a slope of 1/2 passing through the point (-2, 4)?

• y = 1/2x + 5

• y = 1/2x + 4

• y = 2x + 4

• y = 2x + 5

What should you do after finding the y-intercept 'b'?

• Recalculate the slope

• Plot the line on a graph

• Write the final equation y = mx + b

• Check the point on the line
