Question

What is the equation of a line passing through (3,4) and having a slope of -5?

Answer choices:
y=5x+19
y=-5x+11
y=-5x+19
y=-1/5x+19
y=-1/5x+11

Answer 1

use point-slope form and plug in the values you know, i.e., the point and the slope.
then solve for y, which will give you the slope-intercept form.
all of the answers above are in slope-intercept form.

Answer 2

Start with the equation of a line:
$$
y=mx+b
$$
You know m, the slope, it is give as -5, so you just need to find b, the y-intercept:
$$
4=-5(3)+b
$$
Solve for b and you are done!
