What are the slope and the y intercept of the graph of the liner function shown on the grid

kow [346]

To find the slope use the Rise over Run rule
It rises 2 units and runs 1 unit, so your slope is
2 or 2/1

To find the y-intercept just find where the line crosses the y-axis
it crosses at the -4 mark

Your slope is 2 and y-intercept is -4
