I confirm with the answer that k is the slope of the graph<span>. If the variables x and y vary directly when x = 3 and y = 15, then: a. Write an equation that relates x and y.</span>
When you have to divide a fraction, you have to invert the second fraction (4/7 becomes 7/4), and you then multiply the two fractions.
=2/5 ÷ 4/7
=2/5 * 7/4
Multiply the numerators on top
Multiply the denominators on bottom
=(2*7)/(5*4)
=14/20
Simplify by dividing 2 into top & bottom
=7/10
Hope this helps!! :)
simply, R(x)=2x as a function of x.

Answer:
3
Step-by-step explanation:
Slope-Intercept Form: y = mx + b where m = slope and b = y-intercept
In this case, we are trying to find out the slope of the line described by a equation
The slope will be the very first number after the y =
Slope = 3
