Math Problem Statement

Graph the equation y - 2 = -4(x - 1)

Solution

The equation provided in the image is:

y2=4(x1)y - 2 = -4(x - 1)

We will convert this to slope-intercept form y=mx+by = mx + b where mm is the slope and bb is the y-intercept.

Step 1: Distribute the 4-4 on the right-hand side

y2=4(x1)    y2=4x+4y - 2 = -4(x - 1) \implies y - 2 = -4x + 4

Step 2: Add 2 to both sides to solve for yy

y=4x+4+2    y=4x+6y = -4x + 4 + 2 \implies y = -4x + 6

Now, the equation is in slope-intercept form:

y=4x+6y = -4x + 6

  • Slope (m): -4
  • Y-intercept (b): 6

Graphing:

  1. Start by plotting the y-intercept, which is the point (0,6)(0, 6).
  2. Use the slope 4-4, which means "down 4 units for every 1 unit to the right," to plot the next points.

Example Points:

  • From (0,6)(0, 6), move down 4 units and right 1 unit to plot the point (1,2)(1, 2).
  • Repeat to plot other points like (2,2)(2, -2), (3,6)(3, -6), and so on.

Once the points are plotted, draw a straight line through them to represent the equation y=4x+6y = -4x + 6.


Do you need more details or have any other questions?

Here are 5 related questions to consider:

  1. How do you interpret the slope of a line in real-world problems?
  2. What happens to the graph if the slope changes but the y-intercept stays the same?
  3. Can you graph a line without first converting to slope-intercept form?
  4. What are other forms of linear equations besides slope-intercept form?
  5. How do you find the equation of a line given two points?

Tip: Always check the direction of the slope. A negative slope means the line goes downward from left to right!
