First we find the slope between the two given points.
m = (y2 - y1)/(x2 - x1) = (-5 - 2)/(7 - 6) = -7/1 = -7
Now we use the slope-intercept equation of a line.
y = mx + b
We use one point as x and y, and we solve for b.
2 = -7(6) + b
2 = -42 + b
b = 44
The equation is
y = -7x + 44
Answer: f(x) = -7x + 44
3/22 but in a decimal 0.1363
U² + 6u - 27
u² + 9u - 3u - 27
(u - 3)(u + 9)
The standard notation gets bigger. For example, 10³ is bigger than 10² because their standard notation are 1,000 and 100.
