Question

What is an equation of the line, in point-slope form, that passes through the given point and has the given slope?
point: (8, –8); slope: 3

zale101 · Answer

use point slope formula

anonymous · Answer

equation of a line through a point (x1,y1) and slope m is
y-y1=m(x-x1)

zale101 · Answer

$$y-y_1=m(x-x_1)$$

zale101 · Answer

where m is the slope and the (x-x1) is the given point

zale101 · Answer

the Slope (m)=3 and  x1=8  and y1=-8
so plug in into that formula i provided above

elisuzsmith · Answer

y – 8 = 3 (x + 8)

zale101 · Answer

no y-(-8)=3(y+8)
rewrite y-(-8) to y+8

zale101 · Answer

remember that negative and negative is a positive answer

zale101 · Answer

it should be written like this  y+8=3(y-8)

zale101 · Answer

The point–slope form of the equation for a line passing through the point (x1,y1) is given by:
$$y-y_1=m(x-x_1)$$
Assuming (8, –8) = (x1, y1) and m = 3 and substituting the values, we get :
$$y-(-8)=3(x-8)$$
so simplify :
$$y+8=3x-8$$
