Question

Please help .. What is the slope of the line 2x + 5y = -10?

Answer 1

Solve it for y

Answer 2

in general form it is 2x+5y+10=0 so gradient = -a/b therefore it is -2/5

Answer 3

why did you move the equal sign again?

Answer 4

you dont really have to move the = sign but for this question i find that putting the equation in general form to find the gradient is much easier than the gradient intercept form

Answer 5

okay, i thought i had missed something in a lesson :P but thank you for explaining it :)

Answer 6

no problem :)

Answer 7

oh wait one more thing.. is it ....
