Question

The value of 2x + 7, when y =3 is​

Answer 1

Answer:

$\huge\bf\red{Question}$

$\implies2x+7 , y=3$

$\huge\bf\brown{Answer}$

we use the slope intercept form to find slope and y - intercept.

the slope intercept of y =mx+b where m is slope and b is y intercept .

Find the values of m and b using the form y

=mx+b

m=3/2

b=7

.The slope of the line is the value of m, and the y-intercept is the value of b

slope =.3/2

y =7 intercept

Any line can be graphed using two points. Select two x

values, and plug them into the equation to find the corresponding y values.

Graph the line using the slope and the y-intercept, or the points.

y

slope=3/2

intercept =7

now u can plot it on the graph.
