Math Problem Statement

Gambar grafik dari persamaan garis lurus berikut: y = 3x - 5

Solution

The problem in the image asks to graph the line given by the equation:

y=3x5y = 3x - 5

To help you plot the graph, we can calculate a few points by substituting different values of xx into the equation to find corresponding values of yy. Let's calculate some pairs of (x,y)(x, y) values.

  1. For x=0x = 0: y=3(0)5=5y = 3(0) - 5 = -5 So, (0,5)(0, -5) is one point.

  2. For x=2x = 2: y=3(2)5=65=1y = 3(2) - 5 = 6 - 5 = 1 So, (2,1)(2, 1) is another point.

  3. For x=1x = -1: y=3(1)5=35=8y = 3(-1) - 5 = -3 - 5 = -8 So, (1,8)(-1, -8) is another point.

  4. For x=3x = 3: y=3(3)5=95=4y = 3(3) - 5 = 9 - 5 = 4 So, (3,4)(3, 4) is another point.

Now you can plot these points on the given coordinate plane:

  • (0,5)(0, -5)
  • (2,1)(2, 1)
  • (1,8)(-1, -8)
  • (3,4)(3, 4)

Connect the points with a straight line to form the graph of the equation.

Would you like a further detailed explanation, or do you have any questions?

Here are 5 related questions to deepen your understanding:

  1. What is the slope of the line, and how does it affect the graph?
  2. How would the graph change if the equation was y=3x+5y = 3x + 5 instead?
  3. How can you determine the x-intercept of the line?
  4. What is the significance of the y-intercept in the equation y=3x5y = 3x - 5?
  5. How would you graph the line if given the equation in a different form, such as y1=3(x2)y - 1 = 3(x - 2)?

Tip: The slope of a line represents how steep the line is, and it is found by calculating the change in yy divided by the change in xx.
