Answer:
y = 4x - 26
Step-by-step explanation:
The change in y is 4 when the change in x is 1.
So the slope is change in y/change in x = 4/1 = 4
y = mx + b
30 = 4(14) + b
30 = 56 + b
b = - 26
Therefore, y = 4x - 26
Answer:
Option D is correct
Step-by-step explanation:
-4(3x/2 - 1/2) = -15
<=>
-4*3x/2 + (-4)*(-1/2) = -15
<=>
-6x + 2 = -15
Answer: d/dx (f(x)) = 2x + 5
Ok done. Thank to me :>
