What is the equation of the line whose y-intercept is 3 and slope is 1?



y = x - 3

y = x + 3

y = 3x + 1

johnweldon1993 · Answer

$$\large y = mx + b$$

m = slope here
b = y-intercept...so if we are given both we have

$$\large y = x + 3$$

thank you, i have another question.

What is the equation of the line, in general form, that passes through the point (1, 1) and has a y-intercept of 2.



x - y + 2 = 0

x + y - 2 = 0

x - y - 2 = 0
