Consider the equation $y=-1-\frac{9x}{2}$`y`=−1−9`x`2.

Write down the equation of a line whose gradient is $2$2 and crosses the $y$`y`-axis at $\left(0,1\right)$(0,1).

Express your answer in gradient-intercept form.

Write down the equation of the line in gradient-intercept form, given that its slope is $-3$−3 and its $y$`y` intercept is $-2$−2.
