2x -10 = 30
add ten to both sides
2x = 40
divide by two
x = 20
Answer:
The slope between the two given point is -1
Step-by-step explanation:
The rule of the slope between two points (x1, y1) and (x2, y2) is
m = ![\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
Let us use this rule to solve the question
∵ The given points are (-2, 9) and (1, 6)
∴ x1 = -2 and y1 = 9
∴ x2 = 1 and y2 = 6
→ Substitute them in the rule of the slope above
∵ m = ![\frac{6-9}{1--2}](https://tex.z-dn.net/?f=%5Cfrac%7B6-9%7D%7B1--2%7D)
→ Remember (-)(-) = (+)
∴ m = ![\frac{-3}{1+2}](https://tex.z-dn.net/?f=%5Cfrac%7B-3%7D%7B1%2B2%7D)
∴ m = ![\frac{-3}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-3%7D%7B3%7D)
→ Divide up by down
∴ m = -1
∴ The slope between the two given point is -1
