The following equation, y − 8 = 15 (x + 5) is in the slope-intercept form and will be y=15x+83.
<h3>What is a straight line?</h3>A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0.
It is given that the equation is,
y − 8 = 15 (x + 5)
y=15(x+5)+8
y=15x+75+8
y=15x+83
A linear equation has the form y = mx + b in the slope-intercept format.

Answer:
r = 6
Step-by-step explanation:
Given that p varies directly as r, then the equation relating them is
p = kr ← k is the constant of variation
To find k use the condition p = 4, r = 2
k = =
= 2
p = 2r ← equation of variation
When p = 12
12 = 2r ( divide both sides by 2 )
hence r = 6
