5x(2y-3)-(y+8)=13 I believe this is correct
Sry I'm couldn't solve the second one but the ans for the 1st is 504 sq units

Point-slope form of a line is
y=mx+b
where m is the slope and b is your y intercept
So, if the slope is 5, then that is your m value
y=5x+b
To find the value of b, that is just the value of where the line passes the y axis
If you plug in 90 into theta, the expression becomes sin(180), which has a value of zero. Therefore 90 cannot be a solution to this equation. Hope this helps.
