Please answer ASAP! Compare and contrast the graphs of y < -x + 2 and y > -x + 2.

VikaD [51]

The greater than and less than equal signs determine which way the graph is shaded. The graphs follow the same line but are shaded in different directions. y<-x+2 is shaded below the line because the sign is less than (<). y>-x+2 is shaded above the line because the sign is greater than (>).

Write the point-slope form of an equation of the line through the points (-1, 4) and (-2, 2)

jasenka [17]

Answer:

<h3>The answer is option B</h3>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find an equation of a line given two points first find the slope / gradient

Slope of the line using points (-1,4) and (-2,2) is

$m = \frac{2 - 4}{ - 2 + 1} = \frac{ - 2}{ - 1} = 2$

So the equation of the line using point (-1,4) is

Hope this helps you
