Question

What's the equation of a line that passes through point (–1, 3) with a slope of 1?

Question 19 options:

y = –x – 9


y = 3x + 2


y = 12
1
2
x


y = x + 4

Answer 1

equation is y = x+4

Explanation:

m = 1

y = mx + b

3 = 1*(-1)+b

3 = -1+b

b = 4

so

again

y = mx+b

y = 1x +4

so y = x+4
