Answer:
Okay so "y = mx+b is a linear equation that represents a line on a graph; m represents the slope of the line and b is the y-intercept (The y-intercept of this line is the value of y at the point where the line crosses the y axis.)
In y = 1.29x+2, 1.29 is equal to m, so that is your slope.
The 2 is equal to the b so your y-intercept is 2.
Here's a graph to better understand it :)
