Answer:
A. y = 45.25x + 10
Step-by-step explanation:
We can use the points (3, 145.75) and (5, 236.25) to solve.
Find the slope using the formula [ y2-y1/x2-x1 ].
236.25-145.75/5-3
90.5/2
45.25
Find the y-intercept using the formula for slope-intercept form [ y = mx + b ]
y = 45.25x + b
145.75 = 45.25(3) + b
145.75 = 135.75 + b
10 = b
Put everything we solved for into the formula above.
y = 45.25x + 10
Best of Luck!
