Help please? I’m so dumb

Choice C

===============================================

Explanation:

First we need to find the equation of the boundary line. This is the line that separates the shaded region versus the non-shaded region.

The boundary line goes through (0,-5) so this is the y intercept, so b = -5

Another point on the boundary line is (1,-1). The slope of the line through (0,-5) and (1,-1) is m = 4. You can use the slope = rise/run idea or you could use the slope formula to get m = 4.

With m = 4 and b = -5, the y = mx+b equation updates to y = 4x-5

The boundary line has the equation y = 4x-5

Because it is a solid boundary line (instead of dashed) and the shading is above the boundary, this means we change the equal sign to "greater than or equal to"

Therefore we get

Note: a solid boundary line means that points on this boundary are included in the solution set. A dashed boundary line would mean you don't include boundary points in the solution set. So that's why there is a "or equal to" portion in the inequality sign.

29+6=35

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
