Question

What's the equation of the line passing through the points ​(3​,8​) and ​(-2​,-17​)?

Answer 1

y=5x-7

Explanation:

1. First the slope: -17-8/-2-3= -25/-5=5

2. What is your line equation now? y=5x+b

3. Replace the x and y value with one of the coordinate points: 8=5(3)+b

4. Solve for b: 8=15+b -7=b

5. Substitute it in the equation: y=5x-7

Hope this helps!
