Answer:
y = 45x + 7
Step-by-step explanation:
From the given data, we have ordered pairs (2, 97) and (4, 187). We can use them to find the slope, as such:
[tex]m=\frac{187-97}{4-2}=\frac{90}{2}=45[/tex]
We can then use the slope and one of the ordered pairs to find the y-intercept, as such:
[tex]y=mx+b\\97=45(2)+b\\97=90+b\\7=b[/tex]
Therefore, m = 45 and b = 7. We get the equation:
y = mx + b
y = 45x + 7
