Answer:

Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form:
where m is the slope (also called the gradient) and b is the y-intercept (the value of y when x is 0)
<u>1) Plug the gradient into the equation (b)</u>

We're given that the gradient of the line is 4. Plug this into
as m:

<u>2) Determine the y-intercept (b)</u>

Plug in the given point (1,10) as (x,y) and solve for b

Subtract 4 from both sides to isolate b

Therefore, the y-intercept of the line is 6. Plug this back into
as b:

I hope this helps!
Answer:
1. 4
2. y = 4x
Step-by-step explanation:
1.
Divide any y value by its corresponding x value to find the constant of proportionality.
8/2 = 4
Constant of proportionality: 4
2.
Equation of proportional relation:
y = kx, where k is the constant of proportionality.
y = 4x
