Answer:

y=-4x+7

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-3)/(2-1)

m=-4/1

m=-4

y-y1=m(x-x1)

y-3=-4(x-1)

y=-4x+4+3

y=-4x+7

Determine the line described by the given point and slope (0,0) and 2/3

AlekseyPX

Answer:

The line is $y=\frac{2}{3} x$ .

Step-by-step explanation:

Given:

Point and slope (0,0) and 2/3.

Now, to determine the line.

Here the point is:

$(x_{1},y_{1}) =(0,0)$

And the slope is:

$m=\frac{2}{3}$

Now, putting the formula and substituting the value from above to determine the line:

$y-y_{1} = m(x-x_{1})$

$y-0=\frac{2}{3}(x-0)$

$y=\frac{2}{3} x$

Therefore, the line is $y=\frac{2}{3} x$ .
