The rule for a line whose gradient is -4 and y-intercept = 8 is
Step-by-step explanation:
Equation of line slope intercept form is
------------- (1)
Where m is slope or gradient and b is y-intercept
<u>Here</u>
Substituting values in equation (1)
Answer:
-17 x + 60 y + 33
Step-by-step explanation:
3(7-3x+8y)-4(2x-9y-3)
Distribute
21 -9x+24y -8x +36y +12
Combine like terms
21+12 -9x-8x+24y +36y
33 -17x +60y
Rearringing the terms
-17 x + 60 y + 33
