Question

Question:
Write the equation y equals negative 3 x plus 7 in slope-intercept form and identify the slope and y-intercept. Then describe what each value tells you about the graph.

Finding Slope and Y-Intercept from an Equation

This lesson explores the slope-intercept form of a linear equation, $y = mx + b$, using the example $y = -3x + 7$. Students learn to identify the slope and y-intercept directly from the equation, interpret what each value means graphically, and use those values to plot the line accurately.

In this lesson, you will learn to:
• Recognize and define slope-intercept form $y = mx + b$
• Identify the slope and y-intercept from a linear equation written in slope-intercept form
• Interpret the slope as rise over run and explain the direction and steepness of the line
• Use the slope and y-intercept to graph a linear equation on the coordinate plane
