Aline passes through ( 2, -1) and (4,5)
which answer is the equation of the line ?
a) -3x + y = -7
b) -3x + y = 17
c) -3x + 5y = 13
d) -3x + 5y = -13

A)

Step-by-step explanation:

Slope of the line:

Plug in x and y values of any of the points.

Equation of the line:

Subtract 3x from both sides:

A is correct.

the thermometer is precise but not accurate

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
