Answer:

Step-by-step explanation:
slope=(y2-y1)/(x2-x1)
7-5/9-4
2/5
Answer:
4x + 7
Step-by-step explanation:
7x+4-3x+3
First put the like terms together
7x+4-3x+3 = (7x - 3x) + (4 + 3)
= 4x + 7
So we follow the format y=mx+c. we know the y intercept (c) is 2. the gradient is -1/2 which is a fraction. and then substitute
y=mx+c
y=mx+2
y= -1/2x +2
9.54*10^7 is the correct answer
