Question

Consider the function y = -2x + 1 what is the slope (m)? What is the y intercept (b)? Make a quick graph for the equation

Answer 1

Explanation:

Start with the slope intercept equation: y=mx+b

y=-2x+1

m=-2 and b=1

Now draw a graph on your paper, place a point at +1 on the Y axis.

Next, solve for y with x=1.

y=-2(1)+1

y=-2+1

y=-1

Now graph (1,-1)
