Help? and please make sure it’s right :)

Solve the following pair of equations for x and y: ax/b_ by /a= a +b; ax - by = 2ab

If you apply the changes below to the linear parent function f(x)=x what is the equation of the new function vertically stretched by a factor of 3 flip over the x axis

The approximate line of best fit for the given data points, y = −2x − 2, is shown on the graph. which is the residual value when x = –2? a)–2 b)–1 c)1 d)2
