Answer:
The the equation of the line through the points (8, -2) and (5, 5) in slope-intercept form is
![y=-\frac{7}{3} x+\frac{50}{3}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B7%7D%7B3%7D%20x%2B%5Cfrac%7B50%7D%7B3%7D)
Step-by-step explanation:
Let's start by calculation the slope of the line by finding the slope of the segment that joins the two given points (8, -2) and (5, 5):
![slope=\frac{y_2-y_1}{x_2-x_1} \\slope=\frac{5-(-2)}{5-8}\\slope=\frac{7}{-3} \\slope=-\frac{7}{3}](https://tex.z-dn.net/?f=slope%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20%5C%5Cslope%3D%5Cfrac%7B5-%28-2%29%7D%7B5-8%7D%5C%5Cslope%3D%5Cfrac%7B7%7D%7B-3%7D%20%5C%5Cslope%3D-%5Cfrac%7B7%7D%7B3%7D)
Now we use this slope in the general slope-intercept form of a line;
![y=mx+b\\y=-\frac{7}{3} x+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb%5C%5Cy%3D-%5Cfrac%7B7%7D%7B3%7D%20x%2Bb)
and then we calculate the value of the intercept "b" by using one of the given points through which the line must pass (for example (5,5) ), and solving for b:
![y=-\frac{7}{3} x+b\\5=-\frac{7}{3} (5)+b\\5=-\frac{35}{3} +b\\b=5+\frac{35}{3}\\b=\frac{50}{3}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B7%7D%7B3%7D%20x%2Bb%5C%5C5%3D-%5Cfrac%7B7%7D%7B3%7D%20%285%29%2Bb%5C%5C5%3D-%5Cfrac%7B35%7D%7B3%7D%20%2Bb%5C%5Cb%3D5%2B%5Cfrac%7B35%7D%7B3%7D%5C%5Cb%3D%5Cfrac%7B50%7D%7B3%7D)
The the equation of the line is
![y=-\frac{7}{3} x+\frac{50}{3}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B7%7D%7B3%7D%20x%2B%5Cfrac%7B50%7D%7B3%7D)
