X = -2
Answer:
The y intercept is 5
Step-by-step explanation:
The slope intercept form of an equation is
y = mx+b where m is the slope and b is the y intercept
y = -3/2x+b
Substitute the point into the equation and solve for b
8 = -3/2(-2)+b
8 = 3+b
8-3 =b
5=b
The y intercept is 5
Answer:
15
Step-by-step explanation:

The graph is continuous because it is following a decreasing pattern of -15 per day. If the information were put on a data graph the line formed would be straight.
Answer:
1/2
Step-by-step explanation:
8x+4=4x-12x+12
8x+4=-8x+12
16x+4=12
16x=8
x=8/16=1/2
