Step-by-step explanation:
the slope is always the factor of x.
so, m = 5.
to get b we use the point coordinates as x and y values :
3 = 5×2 + b
3 = 10 + b
b = -7
Answer:
y = -8x + 4
Step-by-step explanation:
Using the y = mx +b for the slope intercept form, the m stands for the slope and the b stands for the y-intercept.
In this case, the slope is -8 and the y-int is 4 so we naturally plug those in
Answer:
5 binders
Step-by-step explanation:
3 times 5 binders would be 15$, and since he paid with 20$, that is 5 dollars change
As an algbraic equation:
3x+5=20
3x=15
x=5
You need to calculate it's slope:
y2-y1 = m(x2-x1)
0-5 = m(3-2)
-5 = m
Now, it would be: y-5 = -5(x-2)
Answer:
(5, -21)
Step-by-step explanation:
Plugging in x = 5:
-5(5) + 4 = -21 = y
