Answer:
The matched pairs are:
(A, 4), (B, 1), (C, 2) and (D, 3)
Step-by-step explanation:
The complete question is:
Match each description of an algebraic expression with the symbolic form of that expression
:
A. 2 terms; variables = x and y
B. 3 terms; variables = x and y; constant = 3
C. 2 terms; variable = x; constant = 4.5
D. 3 terms; variables = x and y; constant = 2
1. x - 2y + 3
2. 4.5 - 2x
3. 4.5x + 2 - 3y
4. 4.5y - 2x
Solution:
A. 2 terms; variables = x and y ⇒ 4. 4.5y - 2x
B. 3 terms; variables = x and y; constant = 3 ⇒
1. x - 2y + 3
C. 2 terms; variable = x; constant = 4.5 ⇒ 2. 4.5 - 2x
D. 3 terms; variables = x and y; constant = 2 ⇒ 3. 4.5x + 2 - 3y

Answer:
The equation of the line is y = 3/4x - 1/4
Step-by-step explanation:
To find the equation of this line, start by using the two points with the slope formula to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (2 - 1/2)/(3 - 1)
m = (3/2)/2
m = 3/4
Now that we have the slope, we can use that and either point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 2 = 3/4(x - 3)
y - 2 = 3/4x - 9/4
y = 3/4x - 1/4
Answer:
y = -1/3x
Step-by-step explanation:
To find the slope of the line, you can take two points and use the slope formula.
-2 - 0 = -2, 6 - 0 = 6, -2/6 = -1/3 which is the slope.
You would usually need to find b in y = mx + b but here you don't need b due to their being no y-intercept.
So just substitute -1/3 into y = mx + b
