First set up a proportion
240/160 = 320/200
Cross multiply and if the left equals the right it is similar.
Plug in the 1/2 where the a’s are answer is -3
Answer:
y = -2x -4
Step-by-step explanation:
The equation of a line is y = mx + b, where m is the slope of the line, and b is the y-intercept. We are told that the slope of the line is -2, so we can start with
y = mx + b
y = -2x + b
We can figure out the value of b by plugging in the coordinates of the point given (-2, 0)
0 = -2(-2) + b
0 = 4 + b
Subtract 4 from both sides of the equation
-4 = b
Then plug that value of b back into the equation above:
y = -2x + (-4) or y = -2x -4
12/3 is rational
DescriptionIn mathematics, a rational number is a number that can be expressed as the quotient or fraction
