Question

Write the equation of a line with a slope of 3 and a y-intercept of 1

Answer 1

@mathmale would it be +1 for the y intercept

Answer 2

Yes. The slope-intercept form of the equation of a straight line is y=mx+b.
If you let x=0, then y=1, or +1.

Write the equation of a line with a slope of 3 and a y-intercept of 1:

slope = m = 3;
y-intercept = b = 1

subst. these values into y=mx+b.

Answer 3

y=3x+1

Answer 4

Great.
