x+3y= -15
3y = -15 - x
y = -5 - x/3
intercept form y = -1/3x -5

a level slope equation sounds like this : y = mx = b attempt to get each and every of the variables contained in the right places 5(x-3y)=2(x+3) 5x - 15 y = 2x+6 Subtract 5x from each and every side: - 15 y = -3x + 6 Divide by -15 for each integer y = 3/15x = 6/15 and simplify y = a million/5 x + 2/5 slope = a million/5 y intercept = 2/5

x + 3y = -15
3y = -15 -x
y = -5 - x/3
gradient = -1/3
y intercept = -5

x + 3y = -15
3y = -15 - x
y = (-15 - x)/3
y = -5 -1/3x
y = -1/3x -5

we need to isolate the y so we get
3y = -x - 15
y = -(x/3) - (15/3)
the y-intercept is 15/3 or 5
and the slope is -1/3

x+3y= -15 ---> 3y= -15-x ----> y= -15/3-x/3 ------>
y= -5-(x/3)

y int form is y=mx+b
which wud be y=-1/3x+-15
y int =-15
