Y= m x + b m = slope; b = y-intercept Lecture 16
Y= m x + b m = slope; b = y-intercept Lecture 16
(4, -8) (0, -5) 4 2 2 4 -2 Lecture 16
Y= m x + b m = slope; b = y-intercept Lecture 16
Y= m x + b m = slope; b = y-intercept Lecture 16
y = 4x + 5 Lecture 16
y = 4x + 5 8 (1, 9) 6 (0, 5) 4 2 1 2 -2 -4 Lecture 16
y = 4x + 5 Lecture 16
Solve for y in terms of x 3x + 2y = 6 3x + 2y = 6 2y = 6-3x Subtract 3x from both sides y = (6-3x)/2 Divide both sides by 2 Write in y = mx + b form Lecture 16
Y= m x + b m = slope; b = y-intercept Lecture 16
3x + 2y = 6 Lecture 16
