Answer:

$\dfrac{5}{3}$

Step-by-step explanation:

To find the gradient (slope) of the given linear relation, use arithmetic operations to isolate y:

Given relation:

$3y-5x=10$

Add 5x to both sides:

$\implies 3y-5x+5x=10+5x$

$\implies 3y=5x+10$

Divide both sides by 3:

$\implies \dfrac{3y}{3}=\dfrac{5}{3}x+\dfrac{10}{3}$

$\implies y=\dfrac{5}{3}x+\dfrac{10}{3}$

Slope-intercept form of a linear equation

$y = mx+b$

where:

m is the slope (gradient)
b is the y-intercept

Comparing the rewritten equation with the slope-intercept formula, the gradient (slope) of the given linear relation is ⁵/₃.

Answer:

Not equivalent

Step-by-step explanation:

if we simplify our two equations we get 6x + 2y and 4x + 4y. Which is not equivalent to each other
