Question

write the equation in slope intercept form of the line that has a slope of 2 and contains the point (3, 7)

Answer 1

To do this, you'll have to plot the point (3,7) on your graph, since the slope is 2, from the point (3,7) you'll want to move down 2 and move left 1 and keep going until you hit the y-intercept (crossing the y axis). Slope intercept form is y=mx+b or y=slope*x+y-intercept

Answer 2

what

Answer 3

Ok basically the slope is 2 over 1 (rise over run) so you would start at point (3,7) on a graph and move in reverse until you cross the y axis, in this case you would cross at (0,1) if I figured right, so you'd have a y intercept of 1 since y intercept is where the line crosses when x is 0. Slope intercept form is y=mx+b so your equation is y=2x+1 if you want to learn step by step I can show you with Twiddla there is another method for solving this but this is the easiest I believe just starting out
