Answer:
D is equivalent to the expression.
Step-by-step explanation:
The expression that is given equals 2.8, or 2.8x.
A. This expression equals 1.6x, and 1.6x is not equivalent to 2.8x
B. 0.3x + 3.1 = 3.4x. This doesn't have the answer of 2.8x.
C. 1.3 - 0.3x = 1 or x.
D. 3.1 - 0.3x = 2.8x. D is the answer.
Answer:
y = -2x - 6
Step-by-step explanation:
Use slope-intercept form to start the equation. y2 - y1 / x2 -x1
-6 - 0 / 0 - (-3) = -6 / 3 = m = -2
Then plug m (-2) into your y=mx+b equation.
y = -2x + b
substitute -6 for y value and 0 for x value to find value of b.
-6 = -2(0) + b
simplify
-6 = 0 +b
subtract 0 from both sides
-6 = b
plug b value back into the equation
final equation of line is: y = -2x -6
