Graphs and equations of lines
dmitriy555 [2]

Answer:

a) y = -\frac{3}{4} x + 5

b) y = 6x-18

c) y = \frac{4}{5} x+\frac{19}{5}

Step-by-step explanation:

a) The slope / gradient is the coefficient of x, so for a) it will be y=-\frac{3}{4} x + C.

C is the y-intercept, so the full equation will be y = -\frac{3}{4} x + 5.

b) Again, since the slope is 6, we know the coefficient of x will be 6.

Now, we have a point on the line and so far, we know the equation is y=6x+c. The coordinates of the point are (2,-6). So now we substitute the y and x values into the equation in order to find C.

-6 = 6(2)+C

-6 = 12+C

C = -18

y = 6x-18

c) To find the gradient we must use the formula \frac{rise}{run}.

rise = change in y value

run = change in x value

so, the gradient = \frac{7-3}{4-(-1)} = \frac{4}{5}

Now the equation is y = \frac{4}{5} x +C

Again, to find C we substitute any of the coordinates into the equation. I will use (-1,3).

3 = \frac{4}{5} (-1) +C

3 + \frac{4}{5} =C

C =\frac{19}{5}

so c) is y = \frac{4}{5} x+\frac{19}{5}
