Solution:
We are required to find the y-intercept of y = 0.75 - 0.25x
[tex]\begin{gathered} Given\text{ the general equation of a straight line} \\ y=mx+c \\ m=slope,\text{ c= y-intercept} \\ \\ comparing\text{ the given equation with y=mx+c} \\ y=0.75-0.25x \\ y=-0.25x+0.75 \\ c\text{ = 0.75} \\ \end{gathered}[/tex]The y intercept is at y = 0.75
