Question 56325
List and verify two intercept points (ordered pairs) that are solutions for the equation 5x – 4y = 20?
Let x=0 and solve for y, the y-intercept is the ordered pair: (0,y)
5(0)-4y=20
-4y=20
-4y/-4=20/-4
y=-5
The y-intercept is: (0,-5)
Let y=0 and solve for x, the x-intercept is the ordered pair: (x,0)
5x-4(0)=20
5x=20
5x/5=20/5
x=4
The x-intercept is: (4,0)
Plot the intercepts and connect the dots and you have a graph that looks like:
{{{graph(300,200,-10,10,-10,10,(20-5x)/-4)}}}
Happy Calculating!!!
