Write an equation of a line with the given slope, m = 1 and y-intercept, b = 4

Solution:

Given, slope, m = 1

Y-intercept, b = 4

The equation of a line in slope-intercept form is given by y = mx + b

Put the values of m and b in the above equation,

So, y = (1)x + 4

y = x + 4

Therefore, the equation of a line is y = x + 4.

Example:

Write an equation of a line with the given slope, m = 2 and y-intercept, b = 3

Solution:

Given, slope, m = 2

Y-intercept, b = 3

The equation of a line in slope-intercept form is given by y = mx + b

Put the values of m and b in the above equation,

So, y = (2)x + 3

y = 2x + 3

Therefore, the equation of a line is y = 2x + 3.
