Please look in your text book for this problem Statement   First find the y-intercept value by substituing the slope and coordinates of the

given point in the equation.

y = mx + b                (Slope-intercept form line equation)

1 = 3 + b                  (Substitute 3 for m, 1 for x, and 1 for y)

1 3 = 3 + b 3     (Subtract 3 from each side)

1 3 = 3 3 + b     (Apply Commutative property of addition: a + b = b + a)

1 3 = b                  (Apply additive inverse property: 3 3 = 0)

b = 2                     (Subtract: 1 3 = 2) Now substitute m = 3 and b = 2 slope-intercept form line equation.

y3x + (2)

y3x 2                (Simplify) The equation of the line that passes through the point (1, 1) and has a slope of 3 is

y3x 2. TESTIMONIALS
 "I want to tell you that our students did well on the math exam and showed a marked improvement that, in my estimation, reflected the professional development the faculty received from you.
