Hint: The slope-intercept equation is formed like this: $y = mx + c$, where m is the slope and c is the y-intercept.

2 lines that are parallel to each other have the same slope.

Okay, the thing is, is that im awful at anything to do with algebra so I REALLY need you to explain it to me.

Whoops, you should use the point-slope form instead: y – y1 = m(x – x1), where y1 and x1 are the x and y coordinates of the coord pair, and m is the slope.

Firstly, find the slope of the equation x + y = 10. Then, substitute the values in. Lastly, turn it into the slope-intercept form by algebra, and you have your answer.
