is this graph proportional? _

Slope: 1

Y-Intercept: (0,4)

Equation: y=1x+4

Step-by-step explanation:

To solve for slope you need to pick 2 points on the graph (ex. 2,6 and 4,8 ), then you use the formula to find the slope.

For Y-Intercept you just look for where the line intercepts on the y-axis (ex. 0,4).

If the line doesn't touch the origin (0,0), then it isn't proportional.

For the equation it's y=mx+b or, if its proportional then y=mx. The Y-Intercept will always be b. The slope represents m. The x is the variable.
