Question

Find the equation of the line using exact numbers y=? and x+?

Answer 1

Answer: y=(0,4) x=(0,-2)

Step-by-step explanation: find where the x and y intercepts intersect and plot the points from the line according to the slope

Answer 2

Answer:

The equation of the line is (y=2x+4).

Step-by-step explanation:

Let the coordinates at which line cuts  x axis be : $(x_1,y_1)=(-2,0)$

Let the coordinates at which line cuts y axis be : $(x_2,y_2)=(0,4)$

To find the equation of the line we will use point-slope form from the coordinates (-2,0) and (0,4).

Slope of the line= m

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{4-0}{0-(-2)}=2$

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

$(y-0)=2\times (x-(-2))$

$y=2x+4$

The equation of the line is (y=2x+4).
