First equation Y = -1/2 - 4 Y-Int = -4 Slope = -1/2
To graph the equation the Y-Int goes on the y line of the graph (like in its name) then the slop is -1/2 so you go down -1 and to the right 2 because it’s rise/run the line should be going from left to right down
Second equation Y = 2x + 1 Y-Int = 1 Slope = 2
To graph this equation you put the 1 on the y line (like in its name) then for the slop you go 2 up because it’s not negative it’s positive then you go one to the right because the x mean go over 1 the line should be going from the right to the left down
