Answer:
Step-by-step explanation:
We are asked the equation of the graph which passes through the points at (0,5) and (-3,-4).
Now, we know that the equation of a straight line passing through the points () and (
) is given by
.
So, in our case () ≡ (0,5) and (
) ≡ (-3,-4)
Therefore, the equation of the straight line will be
⇒
⇒ (Answer)
Answer:
<em><u>slope is -7/8</u></em>
Step-by-step explanation:
ok
first remember these to formulas:
and
now insert the points:
= -7/8
slope intercept form:
y - 4 = -7/8(x - (-5)
y - 4 = -7/8(x + 5)
y = -7x/8 - 3/8
