Question

If slope of a line is 4 and y-intercept made by the line is 2 then the equation of line will be __________

(a) y=4x-2

(b) y=4x+2

(c) y=2x+4

(d) y=2x-4

This question was addressed to me in my homework.

Query is from General Equation of a Line topic in chapter Straight Lines of Mathematics – Class 11

Answer 1

Right answer is (b) y=4x+2

To explain: Let general equation of line be y=m*x + c.

Given, m=4 and c=2.

=>y=4x+2
