Math Problem Statement

Graph a linear function with the given slope and y-intercept.

slope: 3, y-intercept: 10

Solution

To graph a linear function with a slope of 33 and a yy-intercept of 1010, we start by using the slope-intercept form of a linear equation, which is:

y=mx+by = mx + b

where:

  • mm is the slope,
  • bb is the yy-intercept.

Substituting the given values:

  • Slope m=3m = 3,
  • yy-intercept b=10b = 10,

the equation becomes:

y=3x+10y = 3x + 10

To graph this:

  1. Start at the yy-intercept point, which is (0,10)(0, 10).
  2. From this point, use the slope to find another point on the line. The slope 33 means a rise of 33 units for every 11 unit run to the right. So, from (0,10)(0, 10), move up 33 units and right 11 unit to get the next point (1,13)(1, 13).
  3. Plot these points and draw a straight line through them.

Here are 5 related questions to consider:

  1. What is the general formula for a linear equation?
  2. How do you interpret the slope and yy-intercept of a line?
  3. What changes in the graph if the slope becomes negative?
  4. How would the graph change if the yy-intercept was 00?
  5. How can you determine if two lines are parallel?

Tip: The slope of a line shows how steep it is; a higher slope means a steeper line.
