point slope form

Multiple Choice

Write the equation of a line that has a y-intercept of -3 and a slope of -4.

• 1.y = -3x – 4

• 1.y = -4x – 3

• 1.y = -3x + 4

• 1.y = -4x + 3

Writing Equations 

• When asked to write an equation, you need to know two things – slope (m) and y-intercept (b).

Writing Equations 

• Write an equation in slope-intercept form of the line that has a slope of 2 and a y-intercept of 6.

• To write an equation, you need two things:

   slope (m) = 2

   y – intercept (b) = 6

• We have both!! Plug them into slope-intercept form

  y = mx + b
