Answer:
y=4x-1
Step-by-step explanation:
If you separate those into points (0,2) and (2,4) then figure out the slope by using the equation y2-y1 divided by x2-x1, you'll get 4-2 over 2-0 which gives you 2/2 or 1. You found the slope so you can plug that into the slope-intercept equation y-y1=m(x-x1). For you, it'd be y-2=1(x-0), you end up with the equation y=x+2.
Start with y = mx + b. Subst. -34 for m and 5 for b: y = -34x + 5
