Answer:
y = - 3x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (5, - 8)
m = =
= - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 1) , then
1 = - 6 + c ⇒ c = 1 + 6 = 7
y = - 3x + 7 ← equation of line
The complete question in the attached figure
we have that
<span>A door to a playhouse is 50 inches tall
we know that
1 in---------------> is 0.0833333 ft
so
50 in-------------> 50*0.0833333---------> 4.167 ft
</span>4.167 ft----------> [4 ft+0.167 ft]
<span>remember that
</span>1 in---------------> is 0.0833333 ft
<span>X in----------------> 0.167 ft
X=0.167/0.0833333----------> X=2 in
therefore
</span>4.167 ft----------> [4 ft+0.167 ft]--------> [4 ft+2 in]<span>
the answer is
the option b) 4 ft 2 in
