Graph the line passing through the given point and having the given slope (0,3), m=4

andriy [413]

<u>Hint </u><u>:</u><u>-</u>

To find out the equation of the line we can use the point slope form of the line which is $y - y_1 = m(x-x_1)$

<u>Solution</u><u> </u><u>:</u><u>-</u>

The given point to us is , $(0,3)$ and the slope of the line is 4 . On using the point slope form , we have ,

$\implies y - y_1= m(x-x_1) \\\\\implies y-3 = 4(x-0) \\\\\implies y -3 = 4x \\\\\implies \boxed{ 4x - y + 3 =0}$

<u>Hence</u><u> the</u><u> </u><u>equation</u><u> </u><u>is </u><u>4</u><u>x</u><u> </u><u>-</u><u> </u><u>y </u><u>+</u><u> </u><u>3</u><u> </u><u>=</u><u> </u><u>0</u><u> </u>
