Y-intercept is the point where the line crosses the y-axis, at this point x=0.
X-intecept is the point where the line crosses the x-axis, at this point y=0.
To identify the x intercept and y intercept, we are going to substitute x=0 and y=0 in the function:
y=7/2(0)-2
y=-2 ---> y-intercept
0=7/2x-2
2=7/2x
2*2/7=x
x=4/7---> x-intercept
