First find the slope of f(x). m=(y2-y1)/(x2-x1) m=(1-5)/(2-0) m=-4/2 m=-2 y=-2x+b, using (2,1) we can solve for the y-intercept, "b" 1=-2(2)+b 1=-4+b 5=b y=-2x+5 So f(x) has a y-intercept of 5 g(x)=6m+3 So g(x) has a y-intercept of 3 h(x)=3x+4 So h(x) has a y-intercept of 4 Then g(x) has the lowest y-intercept of just 3.
Which function below has the lowest y intercept? f(x) graph going through (0, 5) and (2, 1) g(x) Kyle started the summer having read 3 books but plans to read 6 books per month over the summer. h(x) h(x) = 3x + 4
