Which is a factor of 6x^2y + 8x^2 - 30y - 40

Step-by-step explanation:

Equation of a line is given as

y=mx+c

Where

m Is the slope

c is the intercept on the y-axis and at x=0

So from the graph to get the intercept we will look at x=0 and check for y at that point

Prove

y=mx+c

At x= 0

y=m•0 +c

y=c

Then, the intercept is on y axis at x=0

So, from the graph, at x=0, y=0.7

Then, since y=c

Then, c=0.7

The intercept is 0.7
