Answer:
y = - 5x + 16
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 )
Here m = - 5, thus
y = - 5x + c ← is the partial equation of the line
To find c substitute (2, 6) into the partial equation
6 = - 10 + c ⇒ c = 6 + 10 = 16
y = - 5x + 16 ← equation of line
Answer:
90
Step-by-step explanation:
I’m assuming you’re trying to find the equation of a line that intersects the point. In order to do this you need to plug in your points into the equation that at the moment just has your slope.
y=5x —> 13=5(3)+b —> 13=15+b —> 13-15=b
—> b=-2
Now that you finally found your b (y-intercept) you can just plug it in!
y=5x-2

Answer:
B 1.25 hours
Step-by-step explanation:
total cost = flat fee + hourly charge* hours
120 = 45+60*h
We need to solve for h
subtract 45 from each side
120-45 = 45-45+60h
76 = 60h
Divide each side by 60
75/60 = 60h/60
1.25 = h
