Answer:
m= 0.5/1 we write it as -1/2 the rate of change.
So we now know the coordinates are (0.5, 1) we can input the rate of change as m being the slope.
So that m= -1/2 we want to write y = -1/2 * 0.5 x 2 but we start with x+b and show what the equal m and x values.
y = -0.5(x + b)
y = -1/2 * 0.5 + 1.25
y=1
