Activity 1: Equal or Not

We are tasked with:

1. Identifying the slopes (m) and y-intercepts (b) of each linear equation.
2. Comparing the slopes and y-intercepts of the equations to determine if the systems are equal, parallel, or different.

Steps:

1. Rewrite the equations into slope-intercept form $y = mx + b$.
2. Identify the slope ($m$) and the y-intercept ($b$).
3. Compare them for equality.

Problem 1: $x + 2y = 4$

Rewriting: $2y = -x + 4 \implies y = -\frac{1}{2}x + 2$

• Slope ($m$) = $-\frac{1}{2}$
• y-intercept ($b$) = 2

Problem 2: $3x - y = 2$

Rewriting: $-y = -3x + 2 \implies y = 3x - 2$

• Slope ($m$) = 3
• y-intercept ($b$) = $-2$

Problem 3: $x + y = 4$

Rewriting: $y = -x + 4$

• Slope ($m$) = $-1$
• y-intercept ($b$) = 4

Activity 2: Exam Each

We are tasked with determining whether the graphs of each system of equations are:

1. Intersecting
2. Parallel
3. Coinciding

Key Conditions:

• Intersecting: Different slopes ($m_1 \neq m_2$).
• Parallel: Same slope ($m_1 = m_2$) but different y-intercepts ($b_1 \neq b_2$).
• Coinciding: Same slope ($m_1 = m_2$) and same y-intercept ($b_1 = b_2$).
