With the equation of 𝑦=𝑥+3

 

a)  At which point does the graph of the equation cross the x-axis?

b) At which point does the graph of the equation cross the y-axis?

i believe that the questions are essentially asking the values of the x and y intercepts. 

 

to find these, we should plug in the other value as 0, and solve the equation.

 

for example, to solve for the x-intercept, we set y as 0, and then proceed.

 

as a result, we will get 0 = x + 3, and x = -3. so the point that the graph of the equation crosses the x-axis at is (-3, 0).

 

now, to solve for b, we do the same thing, but this time, we plug x in as 0, instead.

 

and we get y = 3. we can conclude that the point the graph of the equation crosses the y-axis at is (0, 3).

 

hope this helped! please let me know if you have any questions :)
