(25 POINTS!!)What is the equation of the line that passes through the points (15,9) and (-2,9)?
Viktor [21]

Let's use the point-slope formula...

<em>y-y1=m(x-x1) </em>

<em>m is the slope. </em>

<em>y--9=7(x--2) </em>

<em>Subtracting a negative number is the same as adding a positive number... </em>

<em>y+9=7(x+2) </em>

<em>y+9=7x+14 </em>

<em>Let's subtract 9 from both sides... </em>

<em>-9+y+9=7x+14-9 </em>

<em>y=7x+5 </em>

<em>The formula is now in the format of... </em>

<em>y=mx+b </em>

<em>This is known as slope-intercept. </em>

<em>m is the slope. </em>

<em>b is the y-intercept, the value of y when x=0. </em>

<em>Standard formula is... </em>

<em>Ax+By=C </em>

<em>Neither A nor B equal zero. </em>

<em>A is greater than zero. </em>

<em>y=7x+5 </em>

<em>Let's move 7x to the left side of the equation.  It becomes negative. </em>

<em>-7x+y=5 </em>

<em>Let's multiply both sides by -1 to render A greater than zero. </em>

<em>-1(-7x+y)=(5)(-1) </em>

<u>7x-y=-5 </u>

<u>This is the equation in standard form.</u>
