Question

4. Point (3, 5) lies on the graph of the equation 3y = kx + 7. The value of k is;
a) 4/3
b) 8/3
c)3
d) 7/3​

Answer 1

Answer:

4/3 is the answer of the equestion of the 3y=Kx +7.

Answer 2

Answer:

If point (3, 5) lies on the graph of the equation

$\sf \: 3y = kx + 7$

then the point will satisfy the equation.

so,

$\sf \: \: \: 3y = kx + 7 \\ \sf \implies \: 3 \times 5 = k \times 3 + 7 \\ \sf \implies \: 15 = 3k + 7 \\ \sf \implies \: 3k = 15 - 7 = 8 \\ \sf \implies \: k = \frac{8}{3}$
