1
Slope-Intercept Form: y = mx + b where m is the slope and b is the y-intercept. How do you know you have b? Either you will see b = ??, or you will be given the ordered pair (0, ??) because the value of x at any y-intercept is 0. How do you find the slope? Either it will be given to you (m = ??), or you can use slope formula: m = when given two ordered pairs. Aim #1.4: How do we write linear equations?
2
a)m = 3, b = -4 b) m = 2/3, b = 7 c) m = 4, (0, -2) d) Passing through (-3, 6 ) and (0, 2) Write the linear equation.
3
You can turn any point-slope form into slope- intercept form by solving, to get y by itself! Formula is: where m,, and are the variables being replaced with your information. You may need to use slope formula to find the slope value. Then, you may choose either ordered pair (if given two) to plug into the formula. Part 2: How do we write linear equations in point-slope form?
4
a)m = -3, (3, -1) b) (-1, 3), (2, 9) c) (4, -1), (6, -7) Part 2: How do we write linear equations in point-slope form?
5
What is the slope of a line and how is it found? Describe how to write the equation of a line if two points along the line are given. Summary: Answer in complete sentences.
6
Extension: Use the figure on the right to answer the following: List the slopes in decreasing order. List the y-intercepts in decreasing order.
