Question

Given the equation y = 5x - 1, what are the intercepts?

Answer 1

y= mx+b

y= 5x-1

x- intercept (y=0)

0= 5x-1

Move -1 to the other side. Sign changes from -1 to +1

O+1= 5x-1+1

1= 5x

Divide by 5 for 1 and 5x

1/5= 5x/5

x= 1/5

y- intercept ( x= 0)

y= 5x-1

y= 5(0)-1

y= -1

Answer : x-intercept = 1/5 and y-intercept = -1 ( third choice)
