Graph 3x + 4y = -10
cricket20 [7]
First, isolate y on one side to find some information about the graph. 

3x+4y=-10 
4y=-10-3x
y=(-10-3x)/4 

Now find out the x and y intercepts of this equation;

(0)=(-10-3x)/4 
4x0=-10-3x 
0=-10-3x 
3x=-10 
x=-10/3 or -3.3333 (x-intercept) 

y=(-10-3(0))/4
4y=-10 
y=-10/4 or -5/2 = -2.5 (y-intercept) 

Plot these points onto your graph and connect the lines. 

I have attached a graph below, I'm sorry I couldn't do it on paper. 

Hope I helped :)

Please help! An archway will be constructed over a walkway. A piece of wood will need to be curved to match a parabola. Explain
Gwar [14]

draw a perpendicular line from the directrix passing through the focus, this will be the line of symmetry. The vertex(h, k) will be located on the line half way between the focus and directrix. The distance from the focus to the vertex is called the focal length, call it a. The then equation is (x - h)^2 = 4a(y - k) the equation can be manipulated to y = 1/4a(x - h)^2 + k hope it helps
