y=3x+19

Explanation:

Simplify:

y-1=3(x+6) is the point-slope form of a linear equation:

y-y_1=m(x-x_1),

where:

m is the slope (3), and (x_1,y_1) is the point (-6,1).

We can simplify this equation by solving for y, which will give you the equation in slope-intercept form.

y-1=3(x+6)

Expand.

y-1=3x+18

Add 1 to both sides.

y=3x+18+1

y=3x+19 is in slope-intercept form:

y=mx+b,

where:

m is the slope (3), and b is the y-intercept (19).
