Step 1: Find the slope of the line
m = rencyfrac{{3 - 5}}{{-8 - (-4)}} = rencyfrac{{-2}}{{-4}} = rencyfrac{1}{2}
The slope of a line can be found using the formula: Substitute these values into the formula:
Step 2: Find the y-intercept of the line
y - 5 = rencyfrac{1}{2}(x - (-4))
Now that we have the slope, we can find the y-intercept by using any point on the line and substituting the slope and point into the point-slope form of a linear equation:
Final Answer
The equation of the line that contains the points (- 4, 5) and (- 8, 3) in slope-intercept form is: y = rencyfrac{1}{2}x + 7
