The slope-intercept form of the equation of a line that passes through point (–3, 8) is y = –x + 6. What is the point-slope form of the equation for this line?

Question

pooja195 · Answer

y=mx+b <----slope intercept form
y=-x+6 <----what is the slope in the equation? 
m=slope

srry the code sucks its supposed to be y= -2/3x+6

pooja195 · Answer

y=mx+b <----slope intercept form
y=-2/3x+6 <----what is the slope in the equation? 
m=slope

allgemeine-klause01 · Answer

-2

pooja195 · Answer

keep in mind that -2/3 is a fraction it belongs together

allgemeine-klause01 · Answer

oh -2/3

pooja195 · Answer

This is point slope form 
$$\huge y-y_1=m(x-x_1)$$
where 
m=-2/3 <---we know this from the slope intercept problem
(x1,y1)
(-3,8)
x1=?
y1=?

x1=-3 y1=8

Good now plug those numbers where they belong into the formula! :) 
$$\huge y-y_1=m(x-x_1)$$
where 
m=slope
(x1,y1)

pooja195 · Answer

We know that:
x1=-3
y1=8
m=-2/3

allgemeine-klause01 · Answer

umm y-8=-2/3(x+3)
