Question

A line has a slope of 1 and passes through the point(2, 8). Whatis its equation in slope-interceptform?

Answer 1

Given:

(2, 8)⇒ x=2 and y=8

Slope(m) = 1

We need to find the intercept (b)

Substitute the points given and the slope(m) into y=mx + b and solve for b

That is;

8 = 1(2) + b

8 = 2+ b

8 - 2 = b

6 = b

Hence, intercept(b) = 6
