Hi

Using the point-slope formula,  to find slope

(–1, 3) and 

(2, –5)   m = 3  -(-5) /-1-2 = 8/-3  Slope m = -(8/3)

the standard slope-intercept form for an equation of a lineis: y = mx + b  

where m is the slope and b the y-intercept.  

y = -(8/3)x + b    | using ordered pair Pt(-1,3) to solve for b

3 = 8/3 + b

1/3 = b

y = -(8/3)x + 1/3

Note: as y increases/decreases by 8, x value changes by 3 in the opposite direction

 The slope will be (change in y)/(change in x)





The slope-intercept form is 

So far I have 

If I substitute (-1,3) in the equation:









The equation is:



check:

does it go through (2,-5) ?







OK
