Answer:
simultaneous linear equations
Step-by-step explanation:
y=7x+3
y=x-3
Answer:
y = x + 6
Step-by-step explanation:
y = mx + b where m = slope and b = y-intercept (where the line crosses the y axis)
To determine the slope (m) take the difference in y value divided by the difference in x value (also called rise over run, or rise/run)
The difference in y value ( or Δ y) in this graph is from 6 to 10, or 4; the difference in x value ( or Δ x) is from 0 to 4, or 4. So since slope = Δy ÷ Δx, the slope is 1.
So we have y = (1)x + b, and b is where the line intercepts the y axis which is at (0,6), so the equation is y = x + 6.
