2 Answers
y-intercept =
Explanation:
Standard form of equation of line is
So simplify the given equation to match
So the y-intercept is
In otherwords, y-intercept is when
this makes:
Explanation:
#"to find the intercepts, that is where the graph crosses"#
#"the x and y axes"#
#• " let x = 0, in the equation for y-intercept"#
#• " let y = 0, in the equation for x-intercept"#

graph{(y+7/2x+6)((x+12/7)^2+(y-0)^2-0.04)((x-0)^2+(y+6)^2-0.04)=0 [-20, 20, -10, 10]}
