Question

What is the equation of a line, in Slope Intercept Form, with a slope of 4 and passes through the point (1, 6)?

Answer 1

The slope-intercept form:

`y=mx+b`

m - slope

b - y-intercept

We have the slope m = 4 →
`y=4x+b`

and point (1, 6). Substitute:

`6=4(1)+b`

`6=4+b` subtract 4 from both sides

`2=b\to b=2`

Answer: y = 4x + 2
