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.

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.

WARM UP ANSWERS 4. First label your points, then substitute the coordinates into the slope formula, and simplify to find the slope. 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. represent the coordinates of the point.
