Answer:
C
Step-by-step explanation:
The slope intercept form of a line is y=mx+b, where m is the slope of the line and b is the y intercept. Therefore, for A, the y intercept is 15, and for C it is -3. For B, the y intercept can be seen to be at -2, and for D it crosses the y axis at 2. Since -3 is the smallest of all of these, the correct answer is C. Hope this helps!
-3/4 also know as negative 3/4
Answer:
60
Step-by-step explanation:
90/100 = 54
Cross multiplying:
100 * 54 / 90
5400/90
60
.7 is 10 times as much as 7
Answer:
y= 8x +7
Step-by-step explanation:
<u>slope-intercept form:</u>
y= mx +c, where m is the gradient (or slope) and c is the y-intercept.
Since it is a linear function, the gradient of any 2 points would be equal.
Thus, gradient of the line
Subst. m=8 into the equation:
y= 8x +c
To find the value of c, substitute a pair of coordinates.
When x=0, y= 7,
7= 8(0) +c
c= 7
Thus, the equation of the linear function is y= 8x +7.
