Question 2. Write a function in the form kx + m when k = 0 and m = 2.
This one bothers me because k=0. If K=0 would the y=kx+m be y=2 (aka remove kx?)
yes, y = 2
y = kx + m , with k=0, m=2
y = 0k + 2 = 2
The confusion probably came from the usual appearance of the equation.
Normally the straight line function takes the form y = mx + b
but it could be
y = ax + z
y = rx + b
y = 😇x + ⏲ , as long as it looks like that pattern, the coefficient of x is the slope
and the constant is the y-intercept.
It does not really matter what variables they use, it is the pattern that matters
btw, your equation of
y = 2
would be a horizontal line with slope of 0 and a y-intercept of 2
that is, a horizontal line 2 units above the x-axis
