<h3>Answer:</h3>

A. y = (-6/5)x +10

<h3>Step-by-step explanation:</h3>

The given line has a negative slope (downward to the right). The only equation offered with a negative slope is the one of selection A.

_____

<em>Complete working</em>

A parallel line will have the same slope. If there are less-obvious choices to select from, you need to know the slope of the given line. That is computed from ...

... slope = (change in y)/(change in x)

The coordinates of two points are given, so we can find the slope as ...

... slope = (-4-2)/(-1-(-6)) = -6/5

There are a number of ways to write the equation of a line, but in slope-intercept form, the slope is the coefficient of x. You will be looking for a choice that has an x-coefficient of -6/5.

Answer:

Step-by-step explanation: There are 12 colours on a spinner,

Probability of red,orange, blue or green = 1/12×4 =4/12

=1/3

Probability of red,blue, orange or green= 1/12×4=1/3

Probability of not red= 1-1/12
