Calculate the constant of variation if y varies directly as x. y = -3 x = 2 answers - 3/2 - 2/3 -1 -6

k = -

Step-by-step explanation:

since y varies directly as x, then the equation connecting them is

y = kx ← k is the constant of variation

to find k use the given condition y = - 3 when x = 2, thus

k = = = -

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

so, converting firstly the mixed fractions to improper fractions and then "adding".
