Answer:
The y-intercept is at y = 10.
Step-by-step explanation:
It will be between y = 14 and y = 7 because the corresponding x values are -2 and 1.
An increase of 3 units of x gives a decrease of 6 units of y fro the above values.
Then an increase of 1 ( 1 to 2) in x gives decrease in y of 2 (8 to 6). The other values show the same pattern.
So very unit increase in x, the y values change by -2.
So from x = -2 to 0 is +2 units for x and this will be -4 units for y so the y-intercept ( when x = 0) will be at y = 14-4 = 10
y-intercept is (0,10).
To a decimal you can round it down to .5 but if its a fraction no.
Answer:
sqrt(21)
Step-by-step explanation:
x = sqrt(7*3) = sqrt(21)
Answer:
No
Step-by-step explanation:
Since x increases exponentially by the 2nd power, it is not linear, it is a quadratic equation.
