Question

What’s the graph answers

Answer 1

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

$-x-2y=-10$    add x to both sides

$-2y=x-10$     divide both sides by (-2)

$y=-\dfrac{1}{2}x+5$

It's a linear function.

We need only two points to plotting a graph.

We choose any three values of x and calculate y.

$\for\ x=0\to y=-\dfrac{1}{2}(0)+5=0+5=5\to(0,\ 5)\\\\for\ x=4\to y=-\dfrac{1}{2}(4)+5=-2+5=3\to(4,\ 3)\\\\for\ x=6\to y=-\dfrac{1}{2}(6)+5=-3+5=2\to(6,\ 2)$
