12,870 dollars. Let me know if you want me to show my work.
Answer:
D. 7
Step-by-Step Explanation:
To solve this problem, we need to know a certain equation: the equation of a line in the slope-intercept form:
y = mx + b; where m = slope and b = y-intercept.
First, substitute the known values into the equation. I will use the coordinate (3, 19) for x and y values.
y = 19
m = 4
x = 3
b = ?
19 = (4)(3) + b
Then, all we have to do is solve for b.
19 = (4)(3) + b
19 = 12 + b
19 - 12 = 12 + b - 12
7 = b
So, the y-intercept of the line is 7.
Hope this helps!
Answer:
12
Step-by-step explanation:
A) m = (y2-y1)/(x2-x1)
m = (4-1)/(-2-(-3))
m = 3/1
m = 3
B) point slope equation : y-y1=m(x-x1)
y - 4 = 3 ( x + 2 )
C) slope intercept equation: y = mx + c
4 = 3(-2) + c
4 = -6 +c
c = 10
Thus, the equation is y= 3x + 10
Answer:
-b - 6
Step-by-step explanation:
4(1 - 2b) + 7b - 10
Apply the distributive property:
4(1 - 2b) + 7b - 10
(4)(1) + (4)(−2b) + 7b + (−10)
4 + (−8b) + 7b + (−10)
Combine like terms:
4 + <u>−8b</u> + <u>7b </u>+ −10
(−8b + 7b) + (4 - 10)
<u>-b - 6</u>
