Question

Write the equation of the line with a slope of -5 and a y-intercept of (0,3)

Answer 1

Put it in point-slope form first.

\(\sf y - y_1 = m(x - x_1)\)

Where \(\sf y_1\) is the y-value of the point, \(\sf x_1\) is the x-value of the point, and \(\sf m\) is the slope.

Answer 2

so 3-0=-5(3-0)

Answer 3

No, we don't do anything to 'x' or 'y'

Answer 4

so

Answer 5

(0, 3)
x1 y1

Answer 6

m = -5

Answer 7

You got the slope right.

\(\sf y - y_1 = -5(x - x_1)\)

Answer 8

okay. so y-3=-5(x-0)

Answer 9

Yep!

Answer 10

and that is the equation?

Answer 11

Yes, do you have choices?

It might want it in slope-intercept form.

Answer 12

nah. I don't think it does because it doesn't say anything about slope intercept
