Question

Write the equation of the line in standard form with a y-intercept of 3 and passes through the point (-2, -7).

Answer 1

equation of the line is:

y = 5x + 3

Explanation:

given co - ordinates are:

x, y = -2, -7

constant, b or y - intercept = 3

standard form of the equation of the line is:

y = mx + b

substituting the given values in the equation to find the slope, m:

-7 = m(-2) + 3

-7 - 3 = -2m

-10/-2 = m

m = 5

thus,

the equation of the line is:

y = 5x + 3
