Question

1. What is the equation of a line in slope-intercept form that has slope -2 and passes through
the point (1, 2)?

Answer 1

You are given the slope of this line, along with one point thru which the line passes. To me this is an invitation to use the point-slope form of the equation of a straight line. Would you do that, please?

Once you have that equation, you can easily re-write it in slope-intercept form.


Alternatively, Frankie, jump directly into the slope-intercept form:

y = m*x + b

We know one point on the line: (1,2), along with the slope, m=-2. Substitute this info into

y = m*x + b and then solve for b.

Finally, write your equation / formula in the form y = m*x + b, using the value of b that you've just calculated.

I got this on my own but thanks
