Question

Write the equation of the line through (2,0) with a slope of -3.

Answer 1

Slope intercept form of a line
\[y=mx+c\]
m= slope of the line
c=intercept
@Katie.bily What's m here?

Answer 2

We know that the equation of a line is y = mx + b.
m is the slope.
Now, we see that it is y = -3x + b
Let's now substitute the given points.
0 = -3(2) + b
0 = -6 + b
b = 6

Now, we know, that b = 6.
Can you frame it now?
