For find f(-2) of f(x)=7x+3, plug in -2 for x.
7(-2)+3=y
-14+3=y
y=-11
To find the rate, or the slope, you divide x/y. So 2/6 is 1/3. 3 over 9 is also 1/3. So the rate is 1/3. In rates you always divide, you don't mulitply or subtract or add to find the rate.
Answer:
The slope is -3/4 y intercept is (0,-5)
Step-by-step explanation:
X Y
-20/3 0
0 5
graph ^
y + 2= -3/4 ( x+4)
Did you already get the answer? If so i am sorry just incase tho i wont answer if you dont have an answer please let me kno ASAP thx :D
Let books =x and games =y
2x+2y=26
4x+1y=28
If you solve for x and y, x=5 and y=8
