Answer:
3
Step-by-step explanation:
Y=mx+b
m=slope
perpendicular lines have slopes that multiply to -1
the line we have is y=-4/7x+5
therefor
if the slope we are looking for is m
(-4/7)m=-1
times -7/4 both sides
m=7/4
we are looking for
y=7/4x+b
last one is answer
Answer:
The y-intercept is the flat fee for the pizza - $5. The slope is the charge for each additional topping - $.50
Step-by-step explanation:
c=.5m+5
y=mx+b - slope intercept formula
In the slope-intercept formula, the 'b' is the y-intercept. We know that would be the flat fee because there is no variable attached to it.
In that formala, m is the slope and is attached to a variable, x. This problem uses the variable m instead of x, but we can see that the slope for .5m would be .5. Thus, that's the charge for the toppings. Hope that helps!
