Answer:
the required equation is y = ( -2/3 )x -7
Step-by-step explanation:
<u>Given</u><u> </u><u>:</u><u>-</u><u> </u>
<em> </em>
<em>the</em><em> line </em><em>passes </em><em>thr</em><em>ough</em><em> </em><em>the </em><em>point</em><em> ( </em><em>0</em><em> , -</em><em>7</em><em> </em><em>)</em>
<em>)and slope of the line is </em><em>(</em><em> </em><em>-</em><em>2</em><em>/</em><em>3</em><em> </em><em>)</em>
<em>• To form an equation when one point and it's slope is given , </em>
<em>• To form an equation when one point and it's slope is given , we use ;</em>
<em>• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )</em>
<em>• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )Where , x and y are variables</em>
<em>• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )Where , x and y are variablesand x1 and y1 are the points where the line meet ! </em>
<em>• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )Where , x and y are variablesand x1 and y1 are the points where the line meet ! and m is slope of the tangent !!</em>
<em>y1</em><em> </em><em>=</em><em> </em><em>-</em><em>7</em>
<em>x1</em><em> </em><em>=</em><em> </em><em>0</em>
<em>So, putting all the values in the equation we get ,</em>
<em></em>
<em></em>
<em>• Slope intercept form of the equation </em>
<em>• Slope intercept form of the equation y = mx + c </em>
<em>• Slope intercept form of the equation y = mx + c Where , m is slope of the line </em>
<em>• Slope intercept form of the equation y = mx + c Where , m is slope of the line and c is y intercept !! </em>
<em>[</em><em> </em><em>also</em><em> </em><em>,</em><em> </em><em>we</em><em> </em><em>can</em><em> </em><em>direc</em><em>tly</em><em> </em><em>put</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>c</em><em> </em><em>=</em><em> </em><em>-</em><em>7</em><em> </em><em>and</em><em> </em><em>m</em><em> </em><em>=</em><em> </em><em>(</em><em> </em><em>-</em><em>2</em><em>/</em><em>3</em><em> </em><em>)</em><em> </em><em>from</em><em> </em><em>given</em><em> </em><em>]</em>
<em>Hence , here m = </em><em>(</em><em>-</em><em>2</em><em>/</em><em>3</em><em> </em><em>)</em><em> and c = </em><em>-</em><em>7</em>
<em>So, the required equation is y = </em><em>(</em><em> </em><em>-</em><em>2</em><em>/</em><em>3</em><em> </em><em>)</em><em>x</em><em> </em><em>-</em><em>7</em>
