The standard equation of a straight line is given as y = mx + b
- m is the slope
- b is the y-intecept
Given the equation y = -2x + 4
- The slope is -2 and the intercept is 4.
Is x = 0, then;
y = -2(0) + 4
y = 4
One of the point on the graph is (0,4)
If x = 1, then;
y = -2(1) + 4
y = -2 + 4
y = 2
Hence the second point is (1, 2)
