Question

Find the slope-intercept form of the equation of a line with slope 1/2 containing point (9,9).
Question 8 options:

x=1/2y+4 1/2

y=1/2x+13 1/2

y=4 1/2x+1/2

y=1/2x+4 1/2

Answer 1

put it into point-slope form and solve for y.

y - y1 = m(x - x1) for a given point (x1, y1) and slope m

Answer 2

y - 9 = .5(x - 9)
y - 9 = .5x - 4.5
y = .5x - 4.5 + 9
y = .5x + 4.5
y = (x+9)/2
