Math Problem Statement

Graph the line with slope 1 passing through the point (-5,2).

Solution

To graph the line with slope 11 passing through the point (5,2)(-5, 2), we use the point-slope form of a line equation:

yy1=m(xx1)y - y_1 = m(x - x_1)

where:

  • m=1m = 1 is the slope,
  • (x1,y1)=(5,2)(x_1, y_1) = (-5, 2) is the given point.

Substitute the values into the equation:

y2=1(x(5))    y2=x+5y - 2 = 1(x - (-5)) \implies y - 2 = x + 5

Now, solving for yy:

y=x+5+2    y=x+7y = x + 5 + 2 \implies y = x + 7

So, the equation of the line is:

y=x+7y = x + 7

This line has a slope of 11 and passes through (5,2)(-5, 2). To graph the line, you can plot the point (5,2)(-5, 2), then use the slope to find another point. Since the slope is 11, for every unit you move to the right, you move up by 11.

Let me know if you would like me to graph this for you or explain further!


Here are five related questions for further exploration:

  1. How would the graph change if the slope was 22 instead of 11?
  2. What is the y-intercept of the line y=x+7y = x + 7?
  3. How would you write the equation of a line with slope 1-1 passing through (0,3)(0, 3)?
  4. How do you determine the slope from two points on a line?
  5. How can you graph a line parallel to y=x+7y = x + 7?

Tip: When using the point-slope form, it's often easier to write the equation of a line if you know the slope and a single point.
