Answer:
y = -0.3x + 103
Step-by-step explanation:
✔️Find the slope (b):
Slope = ∆y/∆x
Using, (25, 95.5) and (35, 92.5),
Slope (m) = (92.5 - 95.5)/(35 - 25) = -3/10 = -0.3
✔️Find the y-intercept (b):
Substitute (x, y) = (25, 95.5) and m = -0.3 into y = mx + b
95.5 = -0.3(25) + b
95.5 = -7.5 + b
95.5 + 7.5 = b
103 = b
b = 103
✔️To write the equation, substitute m = -0.3 and b = 103 into y = mx + b
Thus:
y = -0.3x + 103
Answer:
z=16
Step-by-step explanation:
-7(z-6)= -70
combine -7 with the bracket
-7z + 42 = -70
-42 -42
-7z = - 112
divide both sides by -7
-7z/-7 = -112/-7
z = 16
check
-7(z-6)= -70
-7(16-6)= -70
combine
-112+42= -70
-42 -42
-112 = -112
