You can put this solution on YOUR website! Write the point-slope form of the line satisfying the given conditions. Then use the point-slope form of the equation to write the slope-intercept form of the equation.
Passing through (-9,0) and (0,9).
Type the point-slope form of the equation of the line: =
y-y1 = m(x-x1)
y-0 = [(9-0)/(0--9)](x+9)
y = [9/9](x+9)
y = x + 9
------------------
Type the slope-intercept form of the equation of the line:
y = mx + b
m = (9-0)/(0--9) = 1
Solve for "b":
0 = 1(-9)+b
b = 9
y = 1*x + 9
y = x + 9
