hi First of we could divide via 3 to get the slope-intercept equation. y = (2/3) x + 4. So if we set x=0 we get y=4. to that end the y-intercept is 4 (factor 0,4). additionally be conscious that the equation is in y=mx+b form. b = the y-intercept. Now we could set y = 0. So we get 0 = 2/3 x + 4. Simplified to -4 = 2/3 x. x = -6. So we've the factor -6,0 ---- that's the x intercept. Have a large day

y = 0.5x - 5
The y-intercept is -5. To get the x-intercept, set y=0
0.5x = 5 ... x=10
