Answer: A
Step-by-step explanation:
We need to get this form: 
we need to begin by isolating y on the left side. To do this, we must subtract 4x.
Rewrite it so that we get this form:
Since y needs to be completely isolated, divide by 4.
Divide;
Answer:
A. y=-0.5x-2.5
Step-by-step explanation:
To figure out the equation of a line, use the formula y=mx+b, where x and y are the co-ordinate values, m is the slope and b is the y-intercept (where the line cuts the y-axis).
The slope, m, is calculated by dividing the y-difference (in this case, -2.5) by the x-difference (5): -2.5/5 = -0.5
From the diagram, we can see the line cuts the y-axis at (0,-2.5). Therefore b=-2.5
Sub in our values to get: y=-0.5x-2.5
Answer:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values. Use the graph to find the range.
Step-by-step explanation:
Explanation: y=7 is a straight line with zero slope and y-intercept 7 as shown below. Hence its domain (all allowed x-values) is all real numbers, and its range (all allowed y-values) is only 7.

Answer:
9
Step-by-step explanation:
given an ordered pair (x, y )
Then x is the input and y the output
Given
(1, 9 )
Then y = 9 represents the output
-7,14,-28,<u>5</u><u>6</u><u>,</u><u>-</u><u>1</u><u>1</u><u>2</u>
an = a1(r)^n-1
a4 = -7(-2)^4-1
a4 = -7(-2)³
a4 = -7(-8)
a4 = 56
an = a1(r)^n-1
a5 = -7(-2)^5-1
a5 = -7(-2)⁴
a5 = -7(16)
a5 = -112
