Y-6=-14/11(x+4)
The slope is (6+8)/(-4-7), by the equation y1-y2/x1-x2. This equals -14/11.
In point slope, you follow the form y-y1=m(x-x1) where m is the slope, and x1 and y1 are two points on the coordinate plane. If you substitute in (-4,6), you get the second answer choice, y-6=-14/11(x+4)

(Solving Equations) Ken has $20.00. Coffee costs $4.79 per pound. Which equation will calculate the number of pounds of coffee,

aev [14]

Answer: A. 4.79(n)=20.00

Step-by-step explanation:

we need to find what amount of coffee (per pound) is equivalent to $20.00

so we take the unknown amount (n) and multiply it by $4.79

for example, say Ken wants 4 pounds, we need to know if it is equivalent to $20.00

so take 4.79 and multiply it by 4 to see if it is equal to or less than $20.00 in this case $4.79 x 4 = $19.16

hope this helps (^_^)

What is the equation of the line that passes through the points (−2, 1) and (1, 10)?

Anna71 [15]

Slope = (10-1)/(1+2) = 9/3 = 3

y = mx + b
1 = 3(-2) +b
1 = -6 + b
b = 7

equation

y = 3x + 7
or
3x - y = -7

answer is <span>3x − y = −7 (first choice)</span>
