I need help with my algebra work

Question

What value of n in the equation nx+2=5y would give a line with slope 2

Answer 1

Hello Itai;

The linear equations have the standard form y = mx + b where m is the slope and b is the y-intercept

So, the above equation should be put in this form to find the slope by leaving "y" by itself on one side of the equation.

nx + 2 = 5y ( divide both sides by 5 )

n/5. x + 2/5 = y where n/5 is the slope and 2/5 is the y-intercept

So, if the slope is 2, then n/5 = 2 ==> n = 5 x 2 = 10

Thanks
