Question

write the equation of the line in slope intercept form with the given conditions (slope = 3 and passes through (1,-3))

Answer 1

Because we have a point and slope, we can use at the beginning the point-slope form: y-y1=m(x-x1)

Explanation:

m=3 , x1=1 , y=-3

y-(-3)=3(x-1)

y+3=3x-3 subtract 3 from both sides

y=3x-6 the answer in the slope-intercept form y=mx+b
