Question

Find the equation of the line.
Use exact numbers.
y =_x+7

Answer 1

gradient= -3

Explanation:

Whenever you're calculating a gradient, you use the formula Δy÷Δx so in this case, the change in x will be 1 and the change in y will be -3 as it goes down to meet the line and not up so -3÷1= -3

∴ the gradient(m) = -3

Hope this helps.
