Answer:
Step-by-step explanation:
point-slope formula looks like y-y1 = m(x - x1)
the formula for slope looks like m = (y2-y1) / (x2 - x1)
Memorize both of the above formulas, you'll need them often
along with this slope-intercept formula y = mx + b
Point-slope and slope-intercept do more or less the same things but they are both useful, know them both
we are given 2 points , P1 and P2 , where P1=( -5, 4 ) and P2 = (1,6) side note here: the questions actually gives us 2 tractions, but, I'm pretty sure that it's just a typo and the above is correct, with the points.
then slope m = (y2-y1) / (x2 - x1) where P1 = (x1,y1 ) in our formula and P2 = (x2,y2) in the formula
so plug in P1 and P2
m = (6 - 4 ) / (1 - (-5) )
m = 2 / (1 + 5)
m = 2 / 6
m = 1/3
now use either point P1 or P2, and plug into the point-slope formula, I'll use P1
y - 4 = 1/3(x - (-5) )
y - 4 = 1/3(x + 5 )
