Transform the equation 5x-2y-7=0\, into i)Slope-intercept form ii).Intercept form iii).Normal form.

i)Slope-Intercept form

5x-2x-7=0\,

2y=5x-7\,

y={\frac  {5}{2}}x+{\frac  {-7}{2}}\,

ii).Intercept form

5x-2y-7=0\,

5x-2y=7\,

{\frac  {x}{{\frac  {7}{5}}}}-{\frac  {y}{{\frac  {7}{2}}}}=1\,

iii).Normal form

{\frac  {5x}{{\sqrt  {5^{2}+2^{2}}}}}+{\frac  {-2y}{{\sqrt  {5^{2}+2^{2}}}}}={\frac  {7}{{\sqrt  {5^{2}+2^{2}}}}}\,

{\frac  {5x}{{\sqrt  {29}}}}+{\frac  {-2y}{{\sqrt  {29}}}}={\frac  {7}{{\sqrt  {29}}}}\,
