what is the answer of these equation that is for algebra 1 and I don't know the answer of it y=1/2x+7?

I don't know what you are looking for

but the equation y = 1/2 x + 7 is called slope intercept form, one of the easiest way to draw line/linear graph.

It has slope (m) of 1/2 and y-intercept (b) of 7.

y = mx + b
