Question

Write the equation for the line that goes through the points (-8,2) and (7,7)

Answer 1

y=3x+(0,4.5)

Explanation:

i did this in my head, but the difference between -8 and 7 is 15. the difference between 2 and 7 is 5. it's rise over run so (15,5). that simplified is (3,1)/3. that is the slope. now you need a graph to see the y-int. the y-int is around 4.5.
