Question

How to solve the equation y=1/4x, y= -x+5 by graphing

Answer 1

Answer

(number 1): y=1/4x

Graph the line using the slope and y-intercept, or two points.

Slope:  1/4

y-Intercept: (0,0)

(number 2): y -x+5

Graph the line using the slope and y-intercept, or two points.

Slope:  −1

y-intercept:  (0,5)

(The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be at the point where the two lines intersect.)
