Answer:
The slope intercept form would be y = 9x - 7 and the standard form would be -9x + y = -7
Step-by-step explanation:
To write in either form, we need to start with point-slope form. To get slope-intercept we'll then solve for y.
y - y1 = m(x - x1)
y + 7 = 9(x - 0)
y + 7 = 9x
y = 9x - 7
Now for standard form, we do the same thing, but solve for the constant.
y - y1 = m(x - x1)
y + 7 = 9(x - 0)
y + 7 = 9x
-9x + y + 7 = 0
-9x + y = -7
