Question

Write the equation of the line in slope intercept form and standard form using the given information; m=9,(0,-7)

Answer 1

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
