Hello! I'll write the instructions to graph these functions.
f(x)=x
Technically, this function is y=x, so the slope would be 1. To graph this one, start at the origin (0,0) and move up one unit, and to the right one unit since this is a positive slope.
g(x)= -1/3x+2
First, plot a point at y=2 when x=0. 2 is your y-intercept. Your slope is negative, so the line will be decreasing. From your first point, head down 1 unit and to the right 3 units. Continue plotting points from the previous points.
Also, if you have a graphing calculator, here are the steps to graphing the functions: ON, Y= (enter your functions), and press GRAPH or 2nd, TABLE to see individual points. Hope this helps! :)
Answer:
h = 3.75
Step-by-step explanation:
Step 1: Write equation
2.5/6 = h/9
Step 2: Solve for <em>h</em>
- Cross multiply: 22.5 = 6h
- Divide both sides by 6: 3.75 = h
- Rewrite: h = 3.75
Step 3: Check
<em>Plug in h to verify it's a solution.</em>
2.5/6 = 3.75/9
0.416667 = 0.416667
Answer:
x = 4y + 28
Step-by-step explanation:
x/4 - 7 = y
+7 +7
x/4 = y + 7
× 4 × 4
x = 4y + 28
Answer:
y = 5/8x - 3
Step-by-step explanation:
(8,2) and (-8,-8)
m=(y2-y1)/(x2-x1)
m = ( -8 -2)/ (-8 - 8)
m = (-10)/(-16)
m = 5/8
y - y1 = m(x - x1)
y - 2 = 5/8(x - 8)
y - 2 = 5/8x - 5
y = 5/8x - 3
