Slide 2:
EX Write an equation of the line with a slope of -2 and a y-intercept of 5. y = mx + b y = -2x +5 m = -2 b = 5
Slide 3:
EX Write an equation of the line that passes through the point (-1, 3) and has a slope of -4. y = mx + b (-1, 3)
( x, y) -4 -4 m = -4 b = -1
y = mx + b y = -4x - 1
Slide 4:
EX Write an equation of the line that passes through the point (-3, 0) and has a slope of 1/3. y = mx + b (-3, 0)
( x, y) +1 +1 m = 1/3 b = 1
y = mx + b
