Question

Enter the equation of the line in slope-intercept form.

Slope is -3, and (4,3) is on the line.
The equation of the line is y =

Answer 1

The slope intercept formula y= mx+b .

y= mx+b

We already know the slope which is -3 and plugin 4 for x and 3 for y. Here we are trying to find the y-intercept which is b.

3= -3(4)+b

3= -12+b

+12 +12

15 = b

Here is how it is written in slope- intercept form:

y= -3x+15
