Greetings!

Answer:

The equation is y = 2 - 3x

Explanation:

You can find the gradient by using the gradient formula:

[tex]\frac{y2 - y1}{x2 - x1}

Plug the values in:

[tex]\frac{5 - 2}{-1 - 0}

[tex]\frac{3}{-1}

Which is -3, so the gradient is -3

To find the equation of the line, use the following equation:

y - y1 = m(x - x1)

Where y1 and x1 are just the x and y coordinates in the same set. Let's use (0 , 2)

y1 = 2 , x1 = 0 and m is the gradient, which is -3:

y - 2 = -3(x - 0)

Expand the brackets:

-3 * x = -3x

-3 * 0 = 0

y - 2 = -3x

Move the -2 over to the other side making it a +2:

y = 2 - 3x

So the equation is y = 2 - 3x


Hope this helps!
