Answer:
<h3>mean = 39+ 42+41+38+39+39+42/7</h3><h3>= 244 </h3>
Answer:
Step-by-step explanation:
The top one is the third one the bottom one is the first one
y = 1.4x - 4.8
the equation of a line in ' slope - intercept form ' is
y = mx + c ( m is the slope and c the y- intercept )
the partial equation is y = 1.4x + c
to find c, substitute (2, - 2) into the partial equation
- 2 = 2.8 + c ⇒ c = - 2 - 2.8 = - 4.8
y = 1.4x - 4.8 is the equation in slope- intercept form
