AVprozaik [17]
The centre of the circle will be the midpoint of the two coordinates

\text {Midpoint = }  \bigg( \dfrac{X_1 + X_2}{2} , \dfrac{Y_1 + Y_2}{2} \bigg)

\text {Midpoint = }  \bigg( \dfrac{-3 + 7}{2} , \dfrac{2+ (-2)}{2} \bigg)

\text {Midpoint = }  \bigg( \dfrac{4}{2} , \dfrac{0}{2} \bigg)

\text {Midpoint = }  \bigg( 2, 0 \bigg)

Tell whether the equation −2x + 4y = 5 represents a direct variation. If so, identify the constant of variation.
PtichkaEL [24]
The equation of a direct variation is of the form
y = mx
But the given function can be rewritten as

y =   \frac{1}{2} x +  \frac{5}{4}
This is a partial variation,
\frac{1}{2}
is the constant of variation and

\frac{5}{4}
is the fixed constant.
