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
The temperature fell by 24 degrees in 6 hours. We need to find out how many degrees did the temperature fall every hour.
You can <u>divide</u> 24 with 6.
24 ÷ 6 = 4
Your answer is 4

RS is similar to NM, and TP is similar to OL.
If they're similar they have to be proportional. So:
D.) x = 5, because when you plug five in for x, 5 + 5 = 10 is correct.
