Solution

To find the equation of the line that passes through points A(3,4)A(-3, 4) and B(2,17)B(2, -17), we can use the point-slope form of the equation of a line:

Step 1: Find the slope (mm) of the line

The slope formula is given by: m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1} Where (x1,y1)=(3,4)(x_1, y_1) = (-3, 4) and (x2,y2)=(2,17)(x_2, y_2) = (2, -17).

Substitute the values: m=1742(3)=215m = \frac{-17 - 4}{2 - (-3)} = \frac{-21}{5}

So, the slope of the line is m=215m = -\frac{21}{5}.

Step 2: Use the point-slope form

The point-slope form of a line is: yy1=m(xx1)y - y_1 = m(x - x_1) We can use either point A(3,4)A(-3, 4) or B(2,17)B(2, -17). Let's use point A(3,4)A(-3, 4):

y4=215(x(3))y - 4 = -\frac{21}{5}(x - (-3))

Simplify: y4=215(x+3)y - 4 = -\frac{21}{5}(x + 3) y4=215x635y - 4 = -\frac{21}{5}x - \frac{63}{5} Add 4 to both sides: y=215x635+4y = -\frac{21}{5}x - \frac{63}{5} + 4 Convert 4 to a fraction with denominator 5: y=215x635+205y = -\frac{21}{5}x - \frac{63}{5} + \frac{20}{5} y=215x435y = -\frac{21}{5}x - \frac{43}{5}

Final equation:

The equation of the line is: y=215x435y = -\frac{21}{5}x - \frac{43}{5}

  2. What is the slope-intercept form, and how does it differ from the point-slope form?
  3. How would the equation change if we used point B(2,17)B(2, -17) instead of A(3,4)A(-3, 4)?
  4. How do we interpret the slope of 215-\frac{21}{5} in terms of the line's steepness?
  5. How do we find the x- and y-intercepts of this line?

Tip: Always check your slope calculation first, as it's crucial for getting the correct equation of the line.
