The slope-intercept form: y = mx + b
m - slope
b - y-intercept
We have 2(x - 1) = y + 3 <em>use distributive property</em>
(2)(x) + (2)(-1) = y + 3
2x - 2 = y + 3 <em>subtract 3 from both sides</em>
2x - 5 = y → y = 2x - 5
slope: m = 2
y-intercept: b = -5
x-intercept for y = 0. Substitute:
2x - 2 =0 <em>add 2 to both sides</em>
2x = 2 <em>divide both sides by 2</em>
x = 1
<h3>Answer:</h3><h3>slope = 2</h3><h3>y-intercept = -5</h3><h3>x-intercept = 1</h3>
-------------------------------------------------------------
y = 2x + 1
slope: m = 2
y-intercept: b = 1
x-intercept for y = 0. Substitute:
2x + 1 = 0 <em>subtract 1 from both sides</em>
2x = -1 <em>divide both sides by 2</em>
x = -0.5
<h3>Answer:</h3><h3>slope = 2</h3><h3>y-intercept = 1</h3><h3>x-intercept = -0.5</h3>
