Question

Find the equation of the line containing the point (3,5) and having slope: 4A. y=4x+24B. y=4x+7C. y=4x+17D. y=4x

Answer 1

Data

Point = (3, 5)

slope = 4

Equation of a line

y - y1 = m(x - x1)

m = slope = 4

x1 = 3

y1 = 5

Substitution

y - 5 = 4(x - 3)

Simplifying

y - 5 = 4x - 12

y = 4x - 12 + 5

Result

y = 4x - 7
