Answer:
y= 5x + 3
Step-by-step explanation:
This is because you solve for slope, which is 5, then plug that into point slope form to get:
y - 8 = 5(x - 1)
y - 8 = 5x - 5
y = 5x + 3.
Answer:
y = 5x + 3
Step-by-step explanation:
<em>Step 1</em>. Find the slope
Each time x increases by 1 unit, y increases by 5 units.
m = slope = 5/1 = 5
<em>Step 2.</em> Find the y-intercept.
y = mx + b
When x = 4, y = 23.
23 = 5×4 + b
23 = 20 +b
b = 3
y = 5x + 3
The graph is a straight line with slope m = 5 and a y-intercept at y = 3.
