What is the y-intercept of the line given by the equation below? Enter your answer as an ordered pair.
max2010maxim [7]

The y intercept of given equation y = 2x + 10 is (0, 10)

<em><u>Solution:</u></em>

Given equation of line is:

y = 2x + 10

<em><u>To find: y intercept of the line</u></em>

The point where a line or curve crosses the y-axis of a graph is y intercept

<em><u>Finding y - intercept:</u></em>

To find the y-intercept, plug 0 in for 'x' and solve for 'y'

<em><u>Substitute x = 0 in given equation</u></em>

y = 2(0) + 10

y = 0 + 10

y = 10

Thus the y intercept of given equation is (0, 10)
