Answer:
p = - 115
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
px - 5y = 60 ( subtract px from both sides )
- 5y = - px + 60 ( divide all terms by - 5 )
y = [tex]\frac{1}{5}[/tex] px - 12 ← in slope- intercept form
with slope m = [tex]\frac{1}{5}[/tex] p , thus
[tex]\frac{1}{5}[/tex] p = - 23 ( multiply both sides by 5 to clear the fraction )
p = - 115
