Answer:
2
Step-by-step explanation:
You called this question to the right person. To find the y-intercept, you must do the formula of Point Slope (y-y1 = m (x-x1)) Since 2, is x1 and the -1 is y1, we must lay the equation out like this: y - -1 = m (x-2). Next, we must distribute the slope to the x and the 2, which would allow the x, to fit in with the slope, and the 2 to become 1 since 1/2 x 2 is 1. Now what we need to do is get rid of the -1, so what we do here is add 1. And algebra golden rule, whatever you do to one side, you must do to the other side. This would leave y = 1/2x + 2 And therefore 2 is your y-intercept, since it's at the last part of the equation.
Answer:
false
Step-by-step explanation:
when graphing a proportional relation ship you should be able to draw a straight through all the points
example
For this case we have to by definition, if "y" varies directly with "x" it is represented as:
Where:
k: It is the constant of proportionality
We have to:
We clear the variable "y":
Thus, the constant of proportionality is:
