Substitute value of y from equation (1) in equation (2),
5x-4(5-3x) = -3
5x-20+12x = -3
17x=17
x = 1
Substitute it in equation (1),
y = 5-3(1)
y = 5-3 = 2
So, the values (x,y) = (1,2)
The slope is -4, the y-intercept is 0.
Standard form, move the variables to the left-hand-side, leave the constant on the right-hand-side, usually the "x" comes first,
Place a dot on the 0 spot and draw an arrow facing to the right. The dot must not be filled in. This shows that x>0 because the arrow and dot show the numbers that x can be.
