The point-slope form:

y-y_1=m(x-x_1)

We have

m=2,\ (1,\ 7)

Substitute:

y-7=2(x-1)\qquad|\text{use distributive property}\\\\y-7=2x-2\qquad|+7\\\\y=2x+5\qquad|-5\\\\y-5=2x\qquad|-y\\\\2x-y=-5

<h3>Answer:</h3><h3>point-slope form: y - 7 = 2(x - 1)</h3><h3>slope-intercept form: y = 2x + 5</h3><h3>standard form: 2x - y = -5</h3>

What is the value of c in the equation x^15/x^c =x^6
Galina-37 [17]

Step-by-step explanation:

\frac{ {x}^{15} }{ {x}^{c} }  =  { x}^{6} \\  {x}^{15 - c}  =  {x}^{6}

15 - c = 6

Can someone help me with this problem??
Pavlova-9 [17]
Find the slope first by doing (6+2)/(4-3)=8/1 or just 8. Next use a set of coordinates into the equation so 6=8(4)+b then solve so 6=32+b next subtract 32 from both sides which would equal -24=b. Then plug it all into the equation so y=8x-24
