Answer: y=-3x/4 -1/4
Step-by-step explanation:
y=mx+b
-1=-3/4 * 1 +b
-1=-3/4 + b
(-1=-3/4 + b)*4
-4=-3+4b
4b=-1
b=-1/4
y=-3x/4 -1/4
Input value= number of hours babysat, output value= how much money you get.
Answer:
See below
Step-by-step explanation:
To graph the line we need two points, one point is the y-intercept, the second point to be calculated.
Q7
<u>y = -3x + 6</u>
- The y-intercept is (0, 6)
<u>Let the domain be x = 5 for the second point, then:</u>
- y = -3*5 + 6 = -15 + 6 = -9
- The point is (5, -9)
Connect these points to get the graph
Q8
<u>y = 4/5x - 3</u>
- The y-intercept is (0, -3)
<u>Let the domain be x = 5 for the second point, then:</u>
- y = 4/5*5 - 3 = 4 - 3 = 1
- The point is (5, 1)
Connect these two points to get the graph
Answer:
x=64
y=54
Step-by-step explanation:
3x+4y=24 4(24-4y\3)+3y=22
x=24-4y/3 96-12y\3+3y=22
x=24-4(54)/3
x=-64 96/3-22=3y/3
y=54
