Given equation is y=4.
Question says to graph the given equation y=4 then use the graph to find the missing x- or y-coordinates for the function to the nearest hundredth.
Equation y=4 has no "x" so that means line y=4 will be a horizontal line which passes through 4 on y-axis.
Since it is parallel to x-axis so that means there is no x-intercept.
y-intercept is (0,4) as the line crosses at 4 on y-axis.
ANSWER
EXPLANATION
The required equation passes through:
(4,3) and is perpendicular to x+y=4.
Rewrite the given equation in slope-intercept form:
The slope of this line is -1.
The slope of the required line is perpendicular to this line, so we find the negative reciprocal of this slope.
The equation of the line can be found using:
We substitute the slope and point to obtain:
We simplify to get:
The required equation is
