100 RECYCLE 90% Post Consumer Waste 1) 4 points After two years on the job, an engineer's salary was $60,000. After seven years on the job, her salary was $76,000. Let y represent her salary after x years on the job. Assuming that the change in her salary over time can be approximated by a straight line, give an equation for this line in the form y = mx + b. 2) 4 points | If (x,y) is a point on the parabola y = 3x2, then the tangent line to y = 3x2 passing through (x,y) has slope 6x Find the equation of the line tangent to y = 3x through the point (-2, 12). Give answer in slope-intercept form
