- Slope If a building is 100 feet tall and is viewed from a spot on the ground 70 feet away from the base of the building, what is the slope of a line from the spot on the ground to the top of the building?arrow_forwardYOUR TURN Find an equation of the curve whose tangent line has slope f(x)=3x1/2+4 and passes through the point (1,2).arrow_forwardWe find the ‘steepness,” or slope, of a line passing through two points by dividing the difference in the _______ -coordinates of these points by the difference in the _________-coordinates. So the line passing through the points (0, 1) and (2, 5) has slope _________.arrow_forward
