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)
