How to find the #y#-intercept of the line # y=x+2#?
2 Answers
Explanation:
#"the equation of a line in "color(blue)"slope-intercept form"# is.
#•color(white)(x)y=mx+b#
#"where m is the slope and b the y-intercept"#
#y=x+2" is in this form"#
#"with y-intercept "=2#
graph{x+2 [-10, 10, -5, 5]}
Explanation:
In the slope-intercept form of:
Where: m is the slope and b is the y-intercept, thus in this case:
The slope is 1 and the y-intercept is simply 2.
2nd methode:
To find the x or y intercepts in any form of the equation of the line, simply set y or x to zero and solve for x or y respectively.
For example in this case:
