Hope this explanation helps. :)
Which graph represents a linear function that has a slope of 0.5 and a y-intercept of 2?
2 answers:
The slope-intercept form of line:
y = mx + b
The slope m = 0.5 and y-intercept b = 2. Therefore we have the equation:
y = 0.5x + 2.
It is a linear function. We need only two points to plot the graph.
We have y-intercept, therefore we have the point (0, 2).
Second point:
for x = -4 → y = 0.5(-4) + 2 = -2 + 2 = 0 → (-4 , 0)
