A science experiment begins with a metal at -100° Celsius. The following function describes the temperature change per minute: f(x) = 89x - 100°. How will the graph of this function change if the metal is at 25° at the start of the experiment? The line will shift vertically up by 125°. The line will shift vertically up by 25°. The line will shift vertically down by 125°. The line will shift vertically down by 25°.

    you're actually not solving for anything. y = mx + b is slope-intercept form of a linear function. The function in your problem is written like that. m = slope b = y-intercept. what number is in the "b" spot in your equation?

    ok. so your y-intercept just represents the starting temperature. what would the equation be for a starting temp of 25?

    it moved from -100 to 25. 25 - (-100) = 125
