Step-by-step explanation:
the point-slope form is
y - y1 = m(x - x1)
with (x1, y1) being a point on the line.
so, we have here
y - 4 = 0×(x - -4) = 0
therefore, the resulting equation (which is automatically in slope-intercept form) is
y = 4
this is a flat, horizontal line that passes through (0, 4) on the y-axis, and of course, through (-4, 4), as the y value is 4 for every possible value of x.
Answer:
254.47
A=πr2=π·92≈254.469
the slope is -1/4
the change in y over the change in x from point (-2,-2) to (2,-3) is how to find the slope
y1-y2/x1-x2 = m
-2--3/-2-2 = -1/4
