ANSWER
EXPLANATION
The boundary line passes through (-2,2) and (0,-2).
The slope of this line is
The y-intercept is , c=-2.
The slope-intercept form of this line is given by;
We substitute values to obtain;
Since the lower half-plane is shaded the required inequality is
Hi there! You are provided with two points, this is all you need to calculate the line's slope.
The equation for slope is:
Slope: -2/4
Point slope form, or y-y1 = m(x - x1). All we have to do is take the x and y coordinates of either point, as well as the slope, and plug them into the equation.
y - 10 = -2/4(x - 3)
Write the equation in slope-intercept form (y=mx+b)
A) -2/4
B) y - 10 = -2/4(x - 3)
C) y = -2/4x + 11.5
