Question

find the equation of the line with slope 3 and x-intercept 5?

Answer 1

y=3x-15

Answer 2

help me with my mixed number please

Answer 3

5=3x+b--->b=3x-5

Answer 4

Well, x-intercept means where y=0.
So, if we look at the x-intercept as a point... (x,0), in this case, (5,0)

We can use this and insert it into the slope-intercept form.
\[y = mx + b\]
m = slope, and then we find b. Then, we can just state that y = mx + b is the equation for the line.
