Step-by-step explanation:
I dont know how to do this sorry
x = 18.5, i am sorry if this is wrong
Sure you do !
I'll tell you what it is, and why, and you'll slap your forehead
and call yourself names.
The 'standard' form of an equation that shows the slope and intercept is
y = (slope) x + (intercept)
<em><u>What if the slope is zero</u> ?</em>
Then the equation is y = (0) x + intercept
or
y = intercept.
Does that look anything like y = -3 ?
