The equation of line is y = -3x + 8
<h3>
What is slope?</h3>
Slope is the ratio of the change in the y coordinates to the change in the x coordinates.
Analysis:
slope (m) = y2 - y1 / x2 - x1
m = 14 -5 / -2-1 = 9/-3 = -3
when y = 5, x = 1
y = mx + c
5 = -3(1) + c
5 = -3 + c
c = 5+3 = 8
Y = -3x + 8

Answer:
17,37
Step-by-step explanation:
one number = x
The positive number = 2x + 3
x * (2x+3) = 629
x*2x + x *3 = 629
2x² + 3x - 629 = 0
2x² - 34x + 37x - 17*37 =0
2x*(x -17) + 37(x - 17) = 0
(x - 17)(2x + 37) = 0
x - 17 = 0 ; Ignore 2x + 37 as s is a positive number
x = 17
Positive number = 2*17 +3 = 34+3 = 37
Answer:
<h2>
y+9=-10(x-6)</h2>
Step-by-step explanation:
First you find the slope by setting your y2-y1 over your x2-x1 and that gives you -9-1 / 7-6.
simply that and it gives you -10/1 =-10
then you use the formula y-y1= m(x-x1) . So basically you filling in the blanks
and that gives you y+9=-10(x-6)
