Need help asap dont know answer

Answer 1

Answer:

y=3x +4

Step-by-step 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=$\frac{y1 - y2}{x1 - x2}$

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

➣(0,4) and (2,10)

gradient of the line

$= \frac{10 - 4}{2 - 0} \\ = \frac{6}{2} \\ = 3$

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.
