Question

an equation for the line that crosses x-axis at x=-1 and the y-axis at y=3 is ?
choices are :
a. 3x+y=3
b. 3x=y+3
c. y=3x+3
d. y+3x=-3

Answer 1

Gradient = 3; y-intercept =3



Can you figure out the equation now?

Answer 2

Hint: Use the general form y=mx+c (where m: gradient & c: y-intercept); plug in the values for m & c into the equation.

Answer 3

I didn't get it ?

Answer 4

Use the values for the gradient & the y-intercept in my first post in this thread & plug them into the equation provided in my post above. What do you get as the resulting equation?

Answer 5

is it y=3x+3 ?

Answer 6

Yes, you're correct.
