Answer:
(2a+3 ) (a-4 )=0
Step-by-step explanation:
2a^2 + 8a - 15 = 3a - 3
Subtract 3a from each side
2a^2 + 8a-3a - 15 = 3a-3a - 3
2a^2 + 5a - 15 = - 3
Add 3 to each side
2a^2 + 5a - 15+3 = 3 - 3
2a^2 -5a -12=0
(2a+3 ) (a-4 )=0 These are the factors

Lets say your two points are (2,6) and (-4,7)
To start with you need to use the point-slope formula which is y2-y1/x2-x1
Remember (x,y), Thus we have
7-6/-4-2 = 1/-6; So out slope is -1/6
Now lets use the following equation y = mx+b to solve for b which is the y-intercept. By substitution of either order pair we can solve for b
6 = 2(-1/6)+b; distribute the 2
6 = -2/6+b; add 2/6 to each side to isolate b
6+2/6 = b; put 6 over 1
6/1+2/6 = b; get a common denominator between 6/1 and 2/6 which is 6
6(6/1)+2/6 = b ; distribute
36/6+2/6 = b; add these up
38/6 = b; reduce to lowest terms by dividing by 2 to each
19/3 = b
So our final equation is y = -1/6x+19/3 </span>
