It’s b because if Mandy goes 18 days and her friend goes 3 times the days she goes.
The first part is 8 x 40=320
8 x 7=56
320+56 and i am not sure what you have going on on the other half
Answer:
y = 2x + 2
Step-by-step explanation:
The slope is also called the gradient of the line.
The slope that is given is two, and the point is (1, 4).
I made a point slope equation, and then converted it into a slope-intercept equation.

Hope this helps.
Both these expression are written in slope-intercept form. y = mx + b
m = slope
b = y-intercept
We can find the slope of each expression by finding what m is in each equation.
y = -3x + 2 -> m = -3
y = 4x - 5 -> m = 4
Remember that m = slope
