Answer:
y = m(x-2) + 1
Explanation:
y' = 1, x' = 2(From the graph.
...equation of a straight line is y - y' = m(x - x') where m represent the gradient of the slope.
substitute the values of x' and y' into the line equation.
therefore we have, y-1 = m(x - 2)
Now let's solve for y.
y = m(x-2) + 1
that's it.
