Answer:
1 ) Slope of the line
2 ) Equation of the line
3 ) Values of a and b
a = 5
b = 6
4 ) What is the y-coordinate when?
The y-coordinate is the vertical position of a point in terms of distance and direction along the y-axis.
In this graph, when x = 2 they y-coordinate is also 2 so it is 2 units from the y-axis.
Hope this helps! :)
