graph the function.\n$f(x) = -\frac{1}{5}x + 4$\nuse the line tool and select two points to graph.
Answer
Explanation:
Step1: Find y-intercept
Set ( x = 0 ), then ( f(0)=-\frac{1}{5}(0)+4 = 4 ). So point is ( (0, 4) ).
Step2: Find another point
Set ( x = 5 ), then ( f(5)=-\frac{1}{5}(5)+4=-1 + 4 = 3 ). So point is ( (5, 3) ). (Or other x values, e.g., ( x = 10 ), ( f(10)=-\frac{1}{5}(10)+4=-2 + 4 = 2 ), point ( (10, 2) ); ( x=-5 ), ( f(-5)=-\frac{1}{5}(-5)+4 = 1 + 4 = 5 ), point ( (-5, 5) )) Plot these two points (e.g., ( (0, 4) ) and ( (5, 3) )) and draw a line through them.
Answer:
To graph ( f(x)=-\frac{1}{5}x + 4 ), plot points like ( (0, 4) ) (y - intercept) and ( (5, 3) ) (or other points from substituting x - values) and draw a line through them. (The specific graphing is done by marking two points on the coordinate plane and connecting them with the Line tool.)
