Math Problem Statement

In the coordinate plane, line has a slope of 3 over 5 & passes through the point (-2,6)

Solution

To determine the equation of the line that has a slope of 35\frac{3}{5} and passes through the point (2,6)(-2, 6), we can use the point-slope form of a linear equation:

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

where:

  • mm is the slope of the line
  • (x1,y1)(x_1, y_1) is a point on the line

For this problem, the slope m=35m = \frac{3}{5} and the point is (2,6)(-2, 6). Plugging in these values:

y6=35(x(2))y - 6 = \frac{3}{5}(x - (-2))

Simplify the expression inside the parentheses:

y6=35(x+2)y - 6 = \frac{3}{5}(x + 2)

Next, distribute 35\frac{3}{5}:

y6=35x+35×2y - 6 = \frac{3}{5}x + \frac{3}{5} \times 2

y6=35x+65y - 6 = \frac{3}{5}x + \frac{6}{5}

To solve for yy, add 6 to both sides:

y=35x+65+6y = \frac{3}{5}x + \frac{6}{5} + 6

To combine 65\frac{6}{5} and 6, express 6 as a fraction with a denominator of 5:

6=3056 = \frac{30}{5}

y=35x+65+305y = \frac{3}{5}x + \frac{6}{5} + \frac{30}{5}

y=35x+365y = \frac{3}{5}x + \frac{36}{5}

Thus, the equation of the line is:

y=35x+365y = \frac{3}{5}x + \frac{36}{5}

  4. What would the equation be if the slope were negative instead, say 35-\frac{3}{5}?
  5. How can you find the x-intercept of this line?

Tip: Point-slope form is a very handy tool when you have a point and a slope, as it allows for quick conversion to slope-intercept form!
