Maths Homework - help please ASAP

a curve has equation y=3x(sqred) +6x-7. find the equation of the tangent to the curve at the point x=1, can you please explain what to do

It's perfect except for when you go from the penultimate to the final line, you've made a silly algebra mistake :-)

I'm not sure how you find x and y for part a 😬 can anyone help me please

You can start with either one, so what do you know about one of the co-ordinates when the graph meets the x axis or the y axis?

i'm not sure

We could work with a more simple example and apply the same logic to your question.

If you had the graph $y = x - 5$ and sketched that, where does that cross the x and y axis? What do you notice about one of the co-ordinates in each case?

One of them will be 0

Correct, so now you just have to think: for meeting the x axis, which one will be 0? Same for the y axis, and then find the other co-ordinates.

tou

Can you please help me understand how to do this question please with a step by step process

Question 1 or 2?

1 please

My first step would be to rearrange the equation so you have y on one side. You know how to do that?

no im not sure, i know you have to find m by rearraringing it to y=mx+c but im not sure how to get it
