Answer:
<em>y = 6x + 3</em>
Step-by-step explanation:
<u>Equation of the line</u>
------------------------------------------------------
The equation of the line in slope-intercept form is:
y = mx + b
Being m the slope and b the y-intercept.
Where m is the slope and (h,k) is a point through which the line passes.
We are given the y-intercept as b=3 m=6.
Thus, the equation of the line is:
y = 6x + 3
<span>5x+9=17x-4x+81
-------------------------
Simplify and combine like terms
</span>5x+9=<span>17x+-4x+<span>81
</span></span>5x+9=<span><span>(<span>17x+-4x</span>)</span>+<span>(81<span>)
</span></span></span>5x+9=<span>13x+<span>81
</span></span><span>-----------------------------------
Subtract 13x from each side
</span><span><span>5x+9-</span>13x</span>=<span><span>13x+81-</span><span>13x
</span></span>-8x+9=<span>81
</span><span>-------------------------------------------
Subtract 9 from each side
</span><span><span>-8x+9-</span>9</span>=<span>81-9</span>
<span><span>-8x</span></span>=<span>72
</span><span>------------------------------------------------
And now divide each side by -8
-8x </span>÷ -8 = 72 ÷ -8
<span>x = -9
