What is the slope of the line that passes through the points (-3, 5) and (1, 7)?

just olya [345]

$\bf (\stackrel{x_1}{-3}~,~\stackrel{y_1}{5})\qquad (\stackrel{x_2}{1}~,~\stackrel{y_2}{7}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{7-5}{1-(-3)}\implies \cfrac{7-5}{1+3}\implies \cfrac{2}{4}\implies \cfrac{1}{2}$

F (x) =2x -4; find f (-4)

NemiM [27]

Answer:

f(-4) = -12

Step-by-step explanation:

$f(x)=2x-4$

To calculate f(-4), we need to substitute x in our equation above with -4:

$f(x)=2x-4\\f(-4) = 2*(-4) - 4\\f(-4) = -8-4 = -12$

Note that 2*(-4) = -8

Answer: f(-4) = -12

Answer:

x=7

Step-by-step explanation:

Find slope first

$m-\frac{y2-y1}{x2-x1}$

$m=\frac{6-5}{7-7}$

$m=\frac{1}{0}\\$

m is undefined- so it is a vertical line

x=7
