Using the slope formula, find the slope of the line through the given points. (4.4) and (5.2) What is the slope of the line? Sel
harina [27]

Answer:

A.

m = -1

Step-by-step explanation:

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Simply plug in your 2 coordinates into the formula to find slope <em>m</em>:

m = (6 - 4)/(2 - 4)

m = 2/-2

m = -1

Solve the inequalty 2 2/5 &lt; b-8/15
mr_godi [17]

Answer:

b>44

Step-by-step explanation:

12/5<b-8/15

switch sides b-8/15>12/5

multiply both sides by 15  15(b-8)/15>12*15/5

simplify b-8>36

add 8 to both sides b-8+8>36+8

simplify

b>44

Use the graph to answer the questions in part 1-3.
Tems11 [23]

Answer:

Part 1: m = -7

Part 2: y = -7x -11

Part 3: 7x + y = -11

Step-by-step explanation:

Part 1

Select 2 points, in this case (-2, 3) and (-1, -4) and then use the slope formula

m = (y2 - y1) / (x2 - x1)

m = (-4 -3) / (-1 - -2) =

m = -7/1

m = -7

Part 2

Use the point-slope form equation to find the slope-intercept form

y - y1 = m(x - x1)

y - 3 = -7(x - -2)

y = -7(x +2) +3

y = -7x -14 +3

y = -7x -11

Part 3

Move the x and y to the same side of the equation

y = -7x -11

7x + y = -11
