Question

Find the slope and y-intercept of the lines given below:

(i) y = 3x – 5

(ii) y =$\frac{2}{3}x+4$

(iii) y = –2x + 3

(iv) y = –3x – 5

Answer 1

(i) Given: y = 3x – 5
Here, slope, m = 3 and y-intercept of the line, c = –5

(ii) Given: y =$\frac{2}{3}x+4$
Here, slope, m = $\frac{2}{3}$ and y- intercept of the line, c = 4

(iii) Given: y = –2x + 3
Here, slope, m = –2 and y-intercept of the line, c = 3

(iv) Given: y = –3x – 5
Here, slope, m = –3 and y- intercept of the line, c = – 5
