1) The equation for the slope intercept form of a straight line is:
`y=mx+c` where `m` is the slope and `c` is the y intercept of the line.
Here, `m=7` and `c=-1`
Hence, the required equation is `y=7x-1rArr y-7x=-1`
2) The equation for the point slope form of a straight line is:
`y-y_1=m(x-x_1) ` where,` m` is the slope and `(x_1,y_1)` is a known point.
Here, `m=3` and `(x_1,y_1)=(1,-5)`
Hence, the required equation is `y+5=3(x-1)`
