Question

Which function will start at the y-axis at (0, 7)?
y = 7x
y = x + 7
y = x - 7
y = x + 5

Answer 1

The second equation ( y = x + 7 ) because in the form y= mx + c..... The y-
intercept is c

Answer 2

TO figure out, we need to plug in x=0 and then check if y = 7.

And the answer is B, y = x + 7, because at x=0, we have y = 0 + 7 = 7, which matches the given point (0,7)
