Write an equation of the line that passes through the given point and has the given slope.

ycow [4]

Answer:

y = 1/2x + 1

Step-by-step explanation:

m = 1/2

Slope-intercept:

y - y1 = m(x - x1)

y - 3 = 1/2(x - 4)

y - 3 = 1/2x - 2

y = 1/2x + 1

Step-by-step explanation:

Step 1: Set up Equation

"Nine more" is + 9

"Seven times a number" is 7n

"One more" is + 1

"Square of the [same] number" is n²

7n + 9 = n² + 1

Step 2: Solve for n

Subtract 7n on both sides: 9 = n² - 7n + 1
Subtract 9 on both sides: 0 = n² - 7n - 8
Factor quadratic: 0 = (n - 8)(n + 1)
Solve roots: n = -1, 8
