Write an equation that describes the function

y= –x + 1

Step-by-step explanation:

to write an equation in slope-intercept form, y = mx + b, calculate the slope, m, as rise/ run

The difference in y-values, rise, is –2

The difference between x-values is 2

–2/2 = m, the slope is –1

substitute for m, and it use any set of given y and x values in the equation to solve for b.

y= mx +b

–2 = –1(3) + b. Add 3 to both sides.

3 –2 = 3 –3 + b

1 = b

use the calculated m and b to write the equation with y and x

y = –x + 1

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
