Because the slope doesn't tell you any actual points on the line.
It only tells you whether the line tilts up or down, and how steeply.
But the line could be way up there or way down under, with the same slope.
You can't actually DRAW it until you know some point on it, and
the y-intercept gives you one.
It is to 6km approximately and im in 6th grade <span />
the absolute value of -19 is 19 because the is the "real number" of -19
Point slope is y-y1= m(x-x1) where m is slope
Plug the values in:
y-(-8)=3(x-8)
Simplify:
y+8=3(x-8)
Answer:
11
Step-by-step explanation:
-4x + 7 ; x = -1
-4x (-1) + 7
4 + 7 = 11
