Math Problem Statement

graph y-6=4/5(x-3)

Solution

The given equation is:

y6=45(x3)y - 6 = \frac{4}{5}(x - 3)

To graph this, let's follow these steps:

Step 1: Rewrite in slope-intercept form (y = mx + b)

We'll distribute 45\frac{4}{5} and solve for yy.

y6=45x45×3y - 6 = \frac{4}{5}x - \frac{4}{5} \times 3 y6=45x125y - 6 = \frac{4}{5}x - \frac{12}{5} Now, add 6 to both sides: y=45x125+6y = \frac{4}{5}x - \frac{12}{5} + 6 Convert 6 to a fraction: 6=3056 = \frac{30}{5} So the equation becomes: y=45x+185y = \frac{4}{5}x + \frac{18}{5}

Now, the equation is in slope-intercept form, y=mx+by = mx + b, where:

  • m=45m = \frac{4}{5} is the slope,
  • b=185b = \frac{18}{5} is the y-intercept.

Step 2: Identify the slope and y-intercept

  • Slope (m): 45\frac{4}{5}, which means that for every 5 units you move horizontally (right), you move 4 units vertically (up).
  • Y-intercept (b): 185\frac{18}{5}, which is approximately 3.6.

Step 3: Plot the y-intercept

Start by plotting the y-intercept (0,185)\left(0, \frac{18}{5}\right) or approximately (0,3.6)(0, 3.6).

Step 4: Use the slope to plot another point

From (0,3.6)(0, 3.6), move 5 units to the right and 4 units up. This gives another point on the graph.

Step 5: Draw the line

Draw a straight line through the points.
