How the equation y=7.5x + 50 shows the slope and the y-intercept
iris [78.8K]

Answer:

slope:7.5, y-intercept:50

Step-by-step explanation:

The basic equation for slope is y=kx+b

In this equation, k stands for slope and b stands for y-intercept.

So in y=7.5x+50, k is 7.5 and b is 50 which equal to slope is 7.5 and y-intercept is 50

The mean can be found by adding the two numbers and dividing by 2

let the second number be y

(x + y)/2 = 1/2x + 1

solve for y

multiply each side by 2
x + y = 2(1/2x + 1)
distribute
x + y = x + 2
subtract x on both sides
y = 2

ANSWER: the second number is 2
