Question

Write the equation of the line with a slope of m = 4 and going through the point (1, 3). using y=mx+b

Answer 1

y = mx + b
slope(m) = 4
(1,3)...x = 1 and y = 3
now we sub and find b, the y int
3 = 4(1) + b
3 = 4 + b
3 - 4 = b
-1 = b

ur equation is : y = 4x + (-1) can be written as y = 4x - 1
