find the slope and the y-intercept of the equation y-3=5

Question

anonymous · Answer

First solve for y.
$$y - 3 = 5 \implies y = 8$$Now, this is in the form $y = mx + b$. b is the y-intercept. m is the slope. Notice how the m disappeared. What times anything is 0?

anonymous · Answer

ok i thought the slope was 3 and the y intercepts were (0,5)??

anonymous · Answer

If you look farther into it:
$$y = 0x + 8$$$$y = mx + b$$Do you see how the slope is 0 and how the y-intercept is (0, 8)?

i'm a little confused, but i'm re- reading the lesson maybe i missed something

Ok. When the x-term disappears and it's in the form y = ?, then it's a horizontal line with a slope of 0.
When the y-term disappears and it's in the form x = ?, then it's a vertical line with a slope of undefined.
