Answer:
y = 2x + 4
Step-by-step explanation:
remember the formula of a line: y=mx+b (the y point = the slope times the x point + the y-intercept)
To find the slope:
Remember: slope is rise over run, or the number of units the line goes up, over the amount of units the line goes over. so [tex]\frac{rise}{run}[/tex] (rise over run)
If we start at the leftmost point, we count up 2, over 1 until we get to our next point. Therefore, the slope is 2/1, or 2.
Now to find the y-intercept:
If we assume each square represents 1 unit, the line will intercept the y-axis (or the vertical line) at 4. We know this simply by counting the horizontal lines across the graph until we get to our linear line. We count up 1, 2, 3, 4 until we reach the line.
Put it together in the y = mx + b format, and you get y = 2x + 4
I really hope this helps you understand! Tell me if you need anymore clarification, I'll be happy to help!
