Need help asap dont know answer

Answer 1

y=3x +4

Explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

gradient=
`(y1 - y2)/(x1 - x2)`

Let's choose 2 points on the graph so we can work out the gradient.

➣(0,4) and (2,10)

gradient of the line

`= (10 - 4)/(2 - 0) \\ = (6)/(2) \\ = 3`

Subst. m=3 into the equation.

y= 3x +c

From the graph, the y-intercept is 4. Thus c=4.

Therefore the equation of the graph shown is y=3x+4.
