Find the equation of the line through the points (-2,1) and (5,-20)

Mathematics
1 answer:
ankoles [38]2 years ago
5 0

Answer:

y = -3x - 5

Step-by-step explanation:

First find the slope:  (-20 - 1) / (5 - (-2))  = -3

Then plug in one set of points into the equation y = mx + b.

1 = -3(-2) + b

1 = 6 + b

b = -5

So you can get the equation:  y = -3x - 5

What is the slope of the line that passes through (-5,-2) and ( 7, -2)
denis23 [38]

。☆✼★ ━━━━━━━━━━━━━━  ☾  

slope = difference in y / difference in x

Sub the values in:

slope = (-2- -2) / (7 - -5)

slope = 0 / 12

The slope is 0.

Find f(-1), f(0), f(3) for the following function.<br> f(x)=3x<br> f(-1)=Blank
kramer

Answer:

If f(x) = 3x, this means that any number that replaces x in the parenthesis, would replace x in the right side too.

When x = -1:

f(-1) = 3(-1) = -3

When x = 0:

f(0) = 3(0) = 0

When x = 3:

f(3) = 3(3) = 9
