What is the equation of the line in slope intercept form

Equation of line; y = x + 80

Step-by-step explanation:

As we can see from this graph, point ( 0, 80 ) lying on this graph intersects the y - axis such that it forms a y - intercept of 80;

At the same time we can note that the change in y / change in x, in other words the slope, differs by a rise of 10 / run of 10, 10 / 10 being a slope of 1;

If this equation is in slope - intercept form ⇒

y = a * x + b, where a ⇒ slope, and b ⇒ y - intercept,

Equation of line; y = x + 80
