Answer:
y = 45x + 7
Explanation:
From the given data, we have ordered pairs (2, 97) and (4, 187). We can use them to find the slope, as such:
![m=(187-97)/(4-2)=(90)/(2)=45](https://img.qammunity.org/2020/formulas/mathematics/middle-school/w9lec6honfn45yjwakyf0594nl8ntdu1z2.png)
We can then use the slope and one of the ordered pairs to find the y-intercept, as such:
![y=mx+b\\97=45(2)+b\\97=90+b\\7=b](https://img.qammunity.org/2020/formulas/mathematics/middle-school/jmub6tkgdz1xizx1q4d35vmj7p5b62gwfq.png)
Therefore, m = 45 and b = 7. We get the equation:
y = mx + b
y = 45x + 7
