which statement best describes a line in slope-intercept form when the coefficient of the coefficient of the x term is positive​
lys-0071 [83]

Answer:

The line will be going 'uphill' from left to right

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

y=mx+b

where m is the slope

b is the y-intercept

If the coefficient of the x-term is positive

then

the slope is positive

therefore

If the values of x increases, the values of y increases

If the values of x decreases, the values of y decreases

The line will be going 'uphill' from left to right
