Answer:

\frac{x}{6}  =  \frac{10}{9}  \\   \therefore \: 9 \times x = 6 \times 10 \\ \therefore \:9x = 60 \\ \therefore \:x =  \frac{60}{9}  \\ \therefore \:x =  \frac{20}{3}  \\   \:  \:  \:  \:  \:  \: \huge \red{ \boxed{\therefore \:x =  6\frac{2}{3} }}

I need help I put 30 points for whoever helps me
artcher [175]

Answer:

y=-x+1

Step-by-step explanation:

Slope can be represented as rise over run (change y-values over change in x-values). Since the y-value is changing by -2 every time the x-value is changing by 2, the slope of the line must be \frac{-2}{2}=-1.

In slope-intercept form y=mx+b, m represents the slope of the line, b represents the y-intercept, and (x, y) represent the coordinates of any point the line passes through.

To find b, substitute m=-1 and any point the line passes through.

Using (1, 0) from the table:

0=-1(1)+b,\\0=-1+b,\\b=1

Thus, the equation of this line is \boxed{y=-x+1}
