Question

Write the equation of the line with slope - 1/2 and y-intercept (0, 3). Then graph the line.

Answer 1

y=mx+b
y= -1/2x+3

graph is a line passing through y=3 going up to the left

Answer 2

y = slope times x plus y-intercept
y = -1/2 x + 3

plot (0,3) and (2,2) and draw a line through them. notice (2,2) is down 1 and right 2 from (0,3), which is what the slope tells you.
