y - y1 = m (x - x1)

where m is the slope and (x1 , y1) is the point given

We are given:

m= -1

the point is <span>(2, 4)
</span>

Then:

y - y1 = m (x - x1)
y-4 = (-1) (x-2)
y - 4 = -x + 2
y = -x +2 +4

y = -x + 6

Hope that helps you

Solution of the equation<br> 3x/5+1 = 4x/15+7

Inessa05 [86]

Answer:

$x=18$

Step-by-step explanation:

$\frac{3x}{5} +1=\frac{4x}{15} +7$

$\frac{3x}{5} -\frac{4x}{15} =7-1$

$\frac{9x}{15} -\frac{4x}{15} =6$

$5x/15=6$

$5x=90$

$x=18$

Use the arithmetic sequence of numbers 1, 3, 5, 7, 9,.to find the following:

Rasek [7]

$a)\\\\
a_{n+1}-a_n=d\\
for\ n=1\\
a_2-a_1=d\\
d=3-1=2\ - difference\ between\ two\ consecutive\ terms\\\\
b)\\
a_n=a_1+(n-1)d\\
n=101\\
a_{101}=1+(101-1)*2\\
a_{101}=1+100*2=200+1=201\\\\
c)\\
Sn=\frac{a_1+a_n}{2}*n\\
n=20\\
a_n=a_{20}=1+(20-1)*2=1+38=39\\
Sn=\frac{1+39}{2}*20=400\ \ Sum\ of\ the\ first\ 20 \ numbers.$
