Question

Slope between (9,16) and (11,4)

Answer 1

The answer: m=-6

Explanation:

(9,16)-(11,4)

Answer 2

The equation of the line is y = -6x +70

Explanation:

m is the gradient of the line:
`m=(y_2 - y_1)/(x_2 - x_1)`

So it is 12 ÷ -2 = -6

Then you substitute the value into the equation of a straight line and find the y-intercept.
