Write the slope-intercept form of the equation of each line given the slope and y-intercept. Slope=3, y-intercept= -1

Which is the graph of f(x) = (4)x? image for option 1 image for option 2 image for option 3 image for option 4

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14

Find the measure of angle y. round your answer to the nearest hundredth. ( type the numerical answer only) a right triangle is shown with one leg measuring 5 and another leg measuring 14. an angle across from the leg measuring 5 is marked y degrees. numerical answers expected!
