Select the slope (m) and y-intercept (b). 2x+y=4
Elena L [17]

Answer:

y=-2x+4

Step-by-step explanation:

You want to get y by itself, so you would subtract 2x from both sides giving you, y=-2x+4. -2x is the slope (m), and 4 is the y-intercept (b).

What is the slope of the line that contains the points (–5, 6) and (14, –7)?
Morgarella [4.7K]
\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
%  (a,b)
&&(~ -5 &,& 6~) 
%  (c,d)
&&(~ 14 &,& -7~)
\end{array}
\\\\\\
% slope  = m
slope =  m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-7-6}{14-(-5)}\implies \cfrac{-7-6}{14+5}\implies \cfrac{-13}{19}
