1. WARM UP
1. Explain how to graph a linear equation written in slope-intercept form.
2. Explain how to graph a linear equation written in point-slope form.
3. Explain how to find the y-intercept when given the slope of the line and at least one point that lies on the line and how to write the equation after finding the y-intercept.
4. Explain how to find the slope of a line when given 2 points that lie on the line.
5. Explain how to write a linear equation in point-slope form when given 2 points that lie on the line.

2. WARM UP ANSWERS
1. Start with the y-intercept by plotting the value on the y-axis. Then use the slope to move to the next point to plot. Finally, draw a line through the 2 points.
2. Plot the point in the equation, then use the slope to move to the next point to plot. Finally, draw a line through the 2 points.
3. Substitute the value of the slope and the coordinates of the point into y = mx + b, then solve the equation for b. Finally, write the equation of the line by substituting in the value of the slope and y-intercept into the equation y = mx + b.

3. WARM UP ANSWERS
4. First label your points , then substitute the coordinates into the slope formula,
and simplify to find the slope.
5. Begin by finding the slope of the line. Next, using 1 of the 2 given points substitute the value of the slope and the coordinates of 1 of the 2 points into the point-slope form of a line The
represent the coordinates of the point.
