Algebra is tougher when they make you make up your own problems like this.
Point slope form: That's a line through point (a,b) with slope m,
y - b = m(x-a)
Let's pick point (2,-3) and slope 7,
y + 3 = 7(x-2)
Slope-intercept form: That's a line given slope m and y intercept b,
y = mx + b
We'll pick slope m=3 and y intercept -2:
y = 3x - 2
Standard form: That's ax+by=c or sometimes ax+by+c=0; standard form isn't standard. We'll go with the former, picking some random numbers for a,b,c;
4x - 3y = 5
Let's write all three equations in all three forms
y + 3 = 7(x-2) point/slope
y = 7x - 14 - 3
y = 7x - 17 slope/intercept
7x - y = 17 standard
~~~~~~~~~~
y = 3x - 2 slope/intercept
y + 2 = 3x point/slope
3x - y = 2 standard
~~~~~~~~~~~~~~~
4x - 3y = 5 standard
3y = 4x - 5
y = (4/3) x - (5/3) slope/intercept
y + 5/3 = (4/3) x point/slope
