Weegy: To find a slope in a easy way is to find to points in the line. So plugging in values will help. Plugging in x=1 yields value of y=2(1)+5 = 7, and then next plugging 2 as x, we get y= 2(2)+5=9; so we get two points (1,7) and (2,9) in the line. The formula to find out the slope is - m=(y2-y1)/(x2-x1), again plugging in just found values we get m=9-7/2-1=2/1=2 now things to remember when calculating slop of a line perpendicular to any line is that it has a negative slope regard to the given line, and one more thing is that value also become reciprocal. So in that case it will be = -1/2
User:
What is the slope of a line parallel to the line whose equation is y - x = 5?
-1
1
5
Weegy: y = x + 5
The slope is C.1.
User:
What is the equation of the line whose y-intercept is 3 and slope is 1?
y = x - 3
y = x + 3
y = 3x + 1
User:
What is the equation of a line with a point (-3, 0) and no slope?
x + 3 = 0
y + 3 = 0
x - 3 = 0
y - 3 = 0
