    • Module 4 Topic 3 Writing Linear Equations
      • The equation for slope-intercept form is
      • m is the slope  slope measures the
      • steepness of the line  m=-4/2=-2
      • b is the y-intercept  b is where the
      • line crosses the y-axis.
      -4 2
      • Write the equation of the line that has a
      • slope of -4 and y-intercept of 5 .
    • We use Point-Slope form, when we are given: a point and a slope!
    • Write the equation of the line that passes through (-3,5) and has a slope of 2. What are we given? We are given the slope is 2! AND…we are given a point (-3,5). Final Answer
    • Write the equation of the line that passes through (-3,5) and (-1,9) . What are we given? We are given 2 points, but no slope! Can we find the slope? Do we have enough info? Yes, we can use…
    • Write the equation of the line that passes through (-3,5) and (-1,9) . Now that we know that the slope is 2, we can use either point to find the equation of the line.
      • Summary
      • When given the slope and y-intercept : y=mx+b.
      • When given 1 point and the slope , do point slope: y – y 1 =m(x-x 1 ).
      • When given 2 points, and no slope , one must find the slope (m=y 2 -y 1 over x 2 -x 1) , then use either point for the point slope form.
